Working as a contact center attendant: Relating purpose,meaning,sustainability and mental health

1 Introduction

The economic and social changes of the last decades have provoked deep transformations in business organizations, mainly with the progressive globalization of the production and consumption market [1]. Companies have intensified their search for resource optimization in order to create competitive advantage in the market [2]. The increased pressure for cost reductions through high productivity rates was also achieved with the intensification of work [3]. One of the consequences is the elimination of many jobs promoted by an intensive automation process [4, 5]. Another relevant change was the shift from a predominantly industrial economy to a service economy. Added value is no longer based only on the production and sale of goods, but also on the supply and sale of services [1]. However, the process of streamlining the provision of services is also characterized by intensification of work, with its negative impacts on workers [6]. Thus, the worker in the context of telemarketing (call centers or contact centers) seems to be considered only as a simple adjustment variable of the productive system, being the “factor” that can and should maximize productivity. This is especially true in developing countries like Egypt [7], India [8], Turkey [9], Taiwan [10], and Argentina [11]. A large number of contact center workers are concentrated in Southeast Asia and India [12].

This service sector is characterized by economic and financial gains obtained in a context of tension between work management and organization, and between production and the human dimension of work [13–15]. The work in contact center companies is considered by managers as “simple” and capable of being “executed” from the strict compliance with operating procedures and prescribed scripts, meeting previously established goals. In this scenario, work is precarious, financial rewards are relatively low, and there is lack of support in the relationship between workers and clients. In addition, competition among peers is strongly encouraged, time constraints are high, control is strict regarding scripts and procedures, and unethical behavior is sometimes encouraged [7, 16]. It is a sector characterized by high turnover, influencing the quality and efficiency of work, in addition to generating costs with workers dismissal and admission [17, 18]. It is believed that, over the next years, there will be a robotization of work in the call center, aiming to reduce waiting times and customer dissatisfaction. However, it is assumed that this will not replace the way the process is carried out today, occurring in a combined and complementary way to human work [19]. Exhausting working hours, short and limited intervals between calls, noise, occupational stress, and prolonged voice use with insufficient recovery time are among the main risk factors for the development of diseases for these workers [12].

These characteristics lead to effects on workers’ physical and psychological health and low job satisfaction [9, 20]. For example, working with the public can involve embarrassing situations with verbally aggressive clients, interfering with organizational and worker’s health [21]. Although there may be differences between companies, the need to improve work activities in contact centers is recognized, especially in relation to the psychosocial sphere [22]. In this context, ergonomics and other work-related sciences (such as psychodynamic of work) propose improvements at work. However, telework –of which telemarketing is part –has been a subject little explored in ergonomics [23].

Some studies are focused on improving some working conditions related to physical health problems. One example is the prevention of work-related musculoskeletal disorders among contact center operators [24]. A study carried out in call centers in Sweden found that three out of four operators have local or multiple body pain, especially in the neck, shoulder, arm and hand regions [25]. These disorders originate from static work postures and movement impediments related to sitting work and repetitive upper limbs movements and prolonged computer work [26]. Awareness of the importance of postural variation and breaks is advised [27]. Other physiological dysfunctions have also been reported. For example, Nair et al. [12] observed in a systematic literature review a prevalence of up to 68% of voice problems in call center operators. These problems involved vocal symptoms (such as laryngeal symptoms and vocal respiratory), and musculoskeletal-related symptoms (including hoarse/rough voice, vocal fatigue, effortful voice, and breaks/cracks in voice). Another study investigated the Computer Vision Syndrome in call center operators in Brazil, whose observed symptoms were eye fatigue, “weight” in the eyes, “burning” eyes, tearing and weakening of vision [28].

There are also studies that investigate the relationship between the quality of the physical environment and employee satisfaction [29]. Other studies relate organizational constraints and their impacts on workers’ psychic health. Conflicts in the work environment and health consequences result from psychosocial pressures, including high work intensity and undesirable working hours [30], time pressure causing negative behavior and emotions [31], and working pressure and emotional regulation strategies [32]. Other studies aimed to identify risk indicators for stress and mental energy, relating them to psychosocial working conditions in different call centers [33]. More recent studies evaluated the effects of an ergonomic intervention on physical and mental symptoms of call center workers in Iran [34] and occupational stress and feelings of entrapment in call center workers in Turkey [35].

With a wider vision, ergonomics can contribute in the physical, cognitive, and organizational domain, acting in many work design aspects. Some of them are (a) force, mental well-being and supervisor and peer support acted more in the complexity of the task; (b) inappropriate postures, mental well-being, characteristics of work, supervisor and peer support and the work environment acted on the skill and efforts required; (c) repeatability, workstation design, mental well-being, supervisor and peer support, work environment, and job characteristics acted more on the degree of worker’s control [36]. Most of ergonomics (and work-related sciences) literature related to call center or contact center services focuses on a few specific aspects. It does not provide broader solutions to minimize the negative effects on the intensification of work in contact and call centers. Thus, the objective of this article is to investigate the challenges for a service company (such as a contact center) in reconciling its economic and financial objectives with the promotion of the work dimension, guaranteeing workers the possibility of professional, collective and human development.

To achieve this research objective, we focused on the theoretical contribution that connects ergonomics to business sustainability through rationalities in decision-making processes [37]. There are five main types of rationalities. Instrumental rationality refers to subsequent social decisions and actions based on a rational calculation of means-ends [38, 39]. Substantive rationality promotes decisions and actions based on ethical standards and values not related to results [38, 39]. Communicative rationality promotes cooperation and coordination for decisions that consider the interests of different stakeholders [40]. Bounded rationality consciously recognize human cognitive limitation and the need to consider intrinsic complexities in decisions [41]. Pathic rationality is related to psychic aspects of the work and it is more related to human desires and the perspective of personal achievement, collective issues and the perspective of the contribution to providing satisfaction and minimization of “pathogenic suffering” [42, 43]. Understanding the reasoning used by people who plan and manage work in organizations could explain how the contribution of work-related sciences, such as ergonomics and psychodynamics of work, can improve work in the context of contact centers. These improvements can be concentrated in a developmental perspective, towards propitiating conditions for health and professional improvements. The contribution of ergonomics in the context of this research is to help improve relations between workers and other elements of the system where work is carried out [44]. In this sense, it is pointed out the need for companies not only to increase their own performance, especially in financial terms, but also to improve the well-being of their workers [45]. The psychodynamics of work is aligned with ergonomics, focusing mainly on promoting the mental health of workers, who are “live” subjects in work situations [42]. To support these two disciplines in their application within corporate contexts, the research was supported by the theme of corporate sustainability. This theme, currently well discussed in companies, emphasizes the importance of creating win-win relationships between economic, social and environmental aspects [46]. Taking care of workers is one important objective to promote social sustainability. Workers of different hierarchical levels are needed to effectively introduce corporate sustainability and apply the concepts of ergonomics and work psychodynamics. The present research benefits from the theme of decision for sustainability, especially introducing decisions using substantive and communicative rationalities, and considering human cognitive limitations [37].

2 Method

This research has a qualitative ethnographic approach, following the work analysis method centered on the activity, also known as “Ergonomic Work Analysis” (EWA) [47, 48]. The proposal was to investigate workers’ activities considering the variability in each work situation and the macro organization of work. In this way it is possible to propose changes in the content and working conditions to improve organizational performance and workers’ well-being [45, 49].

This study was carried out in one of the largest companies in the Brazilian contact center market and followed the main steps of an EWA proposed by Guérin et al. [47]. As proposed in Fig. 1 these steps are: (i) demand and context analysis, that is, the organization’s initial requests for ergonomic action (generally related to solve problems inherent to the organization’s performance or worker health) and its organizational context, (ii) exploration of company’s operation, with a general study of the company and delimitation of the situation to be analyzed, (iii) analysis of the technical process and tasks, (iv) analysis of activities and (v) diagnosis. The transformation process was not developed in this study.

In recent years, several studies have used similar methodologies. The analyzes involved documentary research, data collection about activities, interviews, direct observations, verbalizations, interactions through field notes and validation with focus groups [28, 51].

Entering the specific method used for each phase, the first two steps of the EWA (i and ii) were developed through four meeting with the company’s board (an initial meeting lasting four hours with seven participants and another three meetings with the corporate area, totaling ten hours and involving eight participants) and the analysis of documents made available by the company or found on the internet by the team of researchers.

The analysis of the technical process and tasks (iii) was developed mainly with the analysis of technical documents made available by the company and forty-nine semi-structured interviews [52, 53] with managers of the business segment (commercial (two meetings with two people), financial (one meeting with two people), training (one meeting with two people), human resource management (five meetings involving six participants), work organization (fourteen meetings involving twenty six people), health (two meetings involving three people), legal (three meetings involving seven people) and other departments (twenty one meetings involving thirty one people)). Involving only managers, the interviews were carried out from a list of pre-established questions (which may vary according to the interviewee’s area of expertise). Subsequently, the interviews prompts were developed based on the responses obtained from the interviewees. Each interview lasted approximately ninety minutes. The participants were indicated by the company and the interviews were previously scheduled, being recorded according to the authorization of each interviewee. These interviews brought information about corporate segments, power and hierarchy relationship, organization and expected flow of activities, physical space, diversity of work situations, available organizational resources, and tasks prescribed by organization to operational attendants, as well as the criteria for evaluation. From the interviews, it was possible to elaborate the first hypotheses about the dynamic of work.

The activities’ analysis (iv) was carried out mainly through semi-structured interviews, focus groups and free and systematic observations with workers in the operational area (mainly supervisors and attendants). The semi-structured interviews (one involving two supervisors and two involving three operational attendants) focused mainly on the analysis of operational attendants’ activities, especially focused on their exchanges with customers and the use of computerized systems. Questions were raised about different situations, such as strategies for locating the requested information, use of different parts of the software in the same service, interferences of supervisors and people responsible for quality, perception of the workstations, environmental factors, working hours, tricks used by attendants to achieve their goals, etc. Horizontal and vertical communication processes were addressed by research and validated with attendants. Focus groups were organized to address labor issues more collectively and promote discussions among participants to increase participation of different actors in the company. Eleven focal groups were organized (five involving thirty-five supervisors and six involving forty-two operational attendants). The main topic discussed in these groups was the activity performed by different actors and how they deal with different challenges to achieve the goals; questions related to being a leader or managing other colleagues and, finally, questions related to the evaluation of individual and collective performance. Then, free and systematic observations were carried out in six different workplaces with operational attendants. Work positions were selected according to the service situation (intensive, selective, charging, sales or back-office), the attendant (new or experienced) and the diversity of contracts. Thus, customer service, sales, credit recovery, technical assistance and back-office operations were observed. Free observations lasted 12 hours and they were recorded in a field diary. Free observations made it possible to identify workflow structures, physical workspaces, relations between attendants and between them and other actors in the work situation, computerized systems and other tools, variability of production, and attendants’ activities. These observations made it possible to establish specific hypothesis and choose specific work situations, which were centered on systematic observations. Through 16 hours of systematic observations, the activities of five previously chosen operations were observed (which reflected the diversity of systematic contracts). Customer service operations were chosen, with pressure for productivity and intense work pace; sales operations (assets and liabilities) and credit recovery operations, where the pressure for results is intensified; technical assistance operation, which privileges the resolution of user demand, with a less intense work rhythm; and back-office operations, which operate with less direct contact with the user. In general, researchers listened to the conversations between attendants and their customers with headphones and filled some spreadsheets with pre-structured information. Those observations were focused on some specific questions that emerged from the previous (free) observations and related to different hypothesis relating what worker were actually performing on the scenario provided by the tasks. Thus, these observations result in more in-depth information about the different work activities in the company with regard to working conditions and organizational issues, like division of work, difficulties faced by workers, time schedules and performance evaluation. At this stage, an attempt was made to apply discussion groups of operational attendants in the mold promoted by the psychodynamics of work, but the company did not authorize it. Even so, based on the theoretical basis of work psychodynamics, the researchers tried to raise elements that cause suffering and pleasure in the relationship between operational attendants and work organization.

In the diagnosis stage (v), from the qualitative analysis of the collected data, it was possible to identify aspects that were repeated in different operations and specific aspects of a certain group of operations. In this way, it was possible to establish relationships between the impacts on workers and the organization of work. At the end of the EWA, in response to the company’s demand, a diagnosis was prepared addressing issues of work, health and worker performance, and proposals were also presented to transform work situations. As this is a very specific case, the suggestions for improvements in micro-level work situations were not described in this article. However, to achieve the research objective of this study with a macro view, an analysis of the relationships between stakeholders is presented.

RC discloses a commitment to the development of a more sustainable business. In addition, the results of this research showed some negative effects on working conditions caused by work intensification. The EWA diagnostic phase allowed to present some suggestions to improve local working conditions, but as it is a structural problem on the contact center sector, it is important to disseminate the debate among the companies and the society in order to propose actual and effective organizational improvements. Contact center services seem to be basically based on Taylor’s and Ford’s propositions in goods production systems, especially those concerning the “simplification of tasks” and the separation between conception and “execution” [54]. They are not based on principles that consider a perspective of services relationships, which must be based on continuity, trust and other intangible values [55].

The study shows elements that indicate the existence of different types of costs resulting from the intensification of work. Some of them have a negative impact on the company’s economic and financial results, such as those that motivated the initial research demand. The company’s need to solve some legal requirements caused direct costs, such as those related to the obligation to rethink and modify structures or work processes, in addition to being hostage to pecuniary fines or punishments that could affect its operation. Regarding high rates of leaves, turnover and absenteeism, these affect the proper functioning of call centers, negatively impacting the quality and efficiency of the service and increasing costs related to workers. With regard to quality and efficiency, it is important to manage workers so that there are no shortages or excess employees considering demand fluctuations. This can be done with schedules based on algorithms that consider these variations over time in the short and long term. Workers’ preferences, amount of activities and specific days can be considered [17, 18]. Despite the existence of these technological solutions, high rates of absenteeism can compromise, or at least hinder, their efficiency. Regarding the increase in labor costs, there is a direct effect of high turnover rates on hiring and firing costs. However, other costs must be considered, such as those derived from training, since workers need to be continuously trained, and costs with social security [56, 57]. The financial effects related to the satisfaction of final customers should also be considered.

Other costs are externalized to society, such as those related to the illness of workers, which imply expenses for the public health system and for families. Contact center workers have their voice as their main work tool, being susceptible to voice and speech disorders. As they spend a lot of time sitting, other bodily functions, such as musculoskeletal ones, can be affected. In addition, as they are exposed to several psychosocial risk factors, mental disorders have also been reported in the literature, such as depression, anxiety and exhaustion [58–60]. There are also non-monetary costs, such as those related to workers’ loss of motivation to work. Young people can quickly lose the illusion of developing an interesting job, a source of professional and personal development. The presence of “prescribed lies” is particularly critical, causing ethical conflicts among workers.

What is observed is that, even with high internal monetary costs and possible legal penalties for non-compliance with labor legislation, in the current economic context, RC is considered as a successful company. It almost fully meets corporate compliance requirements, seems to satisfy its direct customers (CCs) and generates good financial results for its shareholders. However, if the externalized costs were internalized, it can be assumed that RC’s economic-financial performance would probably be very compromised.

What could be evidenced in this study is that because of strong power relations those who manage contact center companies (the hierarchical superiors, as shown in Fig. 3) can, until today, calculate trade-off that optimizes economic and financial gains, not worrying too much about other costs, especially externalized ones. It seems that in these type of services with highly standardized processes, improving working conditions (even in relation to what is required by legislation) does not pay off economically. The situation analyzed in this customized contact center services showed how RC improves working conditions mainly with the aim of improving productivity of the service provided. These findings may be enough to confirm that work is mainly considered by RC’s managers as an adjustment variable in the service production. The well-being of workers is not a central issue for the company, even if it is disclosed internally. The RC’s decisions are strongly influenced by an instrumental rationality, aimed mainly at maximizing economic and financial gains. This situation is structural in the contact center industry. Without changes in power relations (for example, more public intervention or change in the labor market), or in the prevalence of instrumental rationality in the decision-making process, no significant improvement is expected.

Work-related sciences, especially ergonomics and psychodynamic of work, can suggest ways for a service company (such as contact centers) to reconcile its economic-financial objectives with the promotion of the dimension of work, providing workers with more possibilities for professional, collective and human growth. Ergonomics is traditionally associated with the improvement of local working conditions [61]. However, this association has limited results in transforming working conditions, especially in a context characterized by a great asymmetry of power relations [62] and where decisions are based on an instrumental rationality. Ergonomics actions need to act in a less operational and more strategic discussion, proposing organizational changes [63, 64]. This discipline cannot change structural power relationships with stakeholder but can have impacts by bringing new rationalities in corporate decision-making processes. Its approach that consider the complexity of work system [65] and that promote the participation of different stakeholders allows building a new production model that generates not only desired economic return, but also socio-environmental and cultural development. Psychodynamics of work can contribute especially by bringing a substantive rationality, based on psychoanalytical concepts. Work is considered as the main path to self-fulfillment and health promotion is a central element to the development of culture and of society [66]. These two disciplines can bring new rationales in the corporate decision-making process.

In a substantive rationality, ergonomics and psychodynamics of work consider workers not as a cost, but as active agents that can bring improvements to the process of producing goods and services [55]. Recognition of values associated with work allow the inclusion of the human dimension in the dynamics of the service cycle [67]. In this situation, the worker could play a central role and contribute to the benefit of all actors and society [68]. Promoting the content of the work could promote a balance between those involved in the service cycle. In other words, the promotion of more work-related values, especially worker health and professional development [42, 69] could allow for performance improvements in organizations. However, any action to promote the centrality of work [70] requires a redistribution of power and results, thus requiring a review of the rationality involved in the process (including pathic issues). This path is not being adopted by RC’s managers as well as by the different actors who conceive these work systems. The CCs, by outsourcing services, create conditions to promote a rupture between their production process and the service proposed for FCs, and their relationship becomes mediated by attendants. As there is no direct professional relationship between CCs and attendants, communication and knowledge arising in the contact with FCs are underutilized. In addition, CCs risk their image and their reliability when the outcome of this service relationships generates frustrations in FCs.

Ergonomics also proposes a work situation based on a communicative rationality, with the involvement of all possible stakeholders in corporate decisions [45]. One of the improvements proposed by our team based on the EWA diagnosis was the introduction of a work improvement committee as proposed by the literature connected to ergonomics [71–73]. This study reinforces that the limited communication between planning and operation of the service in RC and between CCs and attendants prevents the consideration of different stakeholders’ interests. Power relations in decision-making processes are not equalized, with economic interests prevailing over socio-environmental interest, which prevents the existence of a truly sustainable and socially responsible environment.

Considering complexity of work systems [65] it is necessary to recognize the presence of limited rationality in decisions. Workers are not an element of production to be managed, they are the only resource in a production system that can be developed [67]. Work is a protagonist in production systems, if we consider the relevance of the actions of different actors in a company, especially if it is possible to understand the importance of human actions at different levels of the hierarchy [68]. Professional competence is even more decisive for the interpretation and understanding of the expectations of the final customers of the service [74, 75]. Thus, the result of the service provided is a shared construction between the worker and the user, based on the conditions provided by the organization [76, 77]. The choices regarding the organization and management of the work in the RC are not neutral, and the work situations created have been reflected in different manifestations of rejection of work and conflicts between managers and employees. Consequently, the development of workers is hampered, and the company has its economic performance more vulnerable. The financial impact can also cause intangible costs. It is also important to consider branding issues, as it is also important for the companies to build and maintain a good image in society. The purpose is to consider workers and professional collectives as active subjects, protagonist in their lives, inside the organization and among society [42, 78].

Summarizing so far, we observed that the presence of large asymmetries in the power relationship between stakeholders allows HSs to act from an instrumental rationality focused on maximizing the economic-financial objectives of the RC. The inclusion of concepts from work-related sciences can bring other rationales in the decision processes of these companies, allowing to add a promotion of the dimension of work, providing workers with more possibilities for professional, collective and human growth. The specific suggestions for improvement pointed out in the diagnosis (and not discussed in the article because they are specific changes in processes and physical structures) were thus useful to promote the dimension of work. However, these changes can bring improvements only in the short term: it was observed that the company was not willing to change current power relations and support organizational changes. However, to really change the observed work situations, where the improvement of a particular situation causes the aggravation of the other, it is important to change decision-making processes. It is in this context that the knowledge of work-related sciences was connected with organizational structures already present in companies, such as those related to corporate sustainability. This connection is already being recognized in the literature, especially between ergonomics and sustainability [79], a technical committee was even formally constituted in the context of the International Ergonomics Association [80]. With a focus on labor issues, ergonomics proposes concepts aligned and very similar to those of sustainability, especially because the social requirements of the triple bottom line are linked with the sustainability of work [79]. As also proposed from corporate sustainability literature, it is suggested to include other stakeholders interests in the creation of corporate value [81], and not just the private financial interests of shareholders [82]. In particular, workers can be key actors for the success of organizations when new rationales are introduced into decision-making processes [37]. From this process, it is expected the creation of new niches of contact center services, with the opportunity to effectively meet the needs of FCs to build stronger and longer-term relationships.

A sustainable approach could help to transform these scenarios, proposing to consider the interests of different stakeholders. Attendants are considered as “generic workers”, not as people who could develop themselves and develop the profession, in a collective and long-term perspective. The introduction of corporate sustainability policies does not just mean transforming some actions into a win–win in relation to the dimensions of the triple bottom line [83]. We note that RC is following this path, documenting its actions in its sustainability reports, but working conditions are marginally improved, remaining precarious. This case study confirms that it would be necessary to introduce other values into the decision-making processes of all stakeholders. The first step must be the recognition of all decision makers who are acting with limited rationality, so that they can take into account the interests and needs of other stakeholders. In addition, values related to sustainability should be disseminated, such as respect for the environment, improving the quality of life of all people (including workers), altruism and a sense of community, in addition to seeing economic value as a means and not as an end [82]. The personal decisions of the different stakeholders can benefit from the adoption of a substantive or axiological rationality, which is not considered by the managers of the studied company. Focusing on work issues, it was observed that, despite the attempts, the quality of life of RC workers is not improving, there has not been an effective appreciation of the sense of community. By disseminating these values throughout the system, it would be possible to establish relationships based on a more cooperative attitude among all stakeholders. In this context, decisions would result from a communicational process, where, through communication between stakeholders, subjective rationality would be considered to include more variables in decisions. There will always be win-lose cases, where a decision may have advantages for one stakeholder and disadvantages for another, but it is believed that existing trade-offs would improve over time. In short term, companies would likely decrease their economic and financial gains, but in the long term it is possible that economic gains would be created even greater than today, especially if positive externalities are considered as economic values [84]. It is also important to consider other rationalities as bases for improving the relationship between companies and society; communication values such the prevalence of truth rather than communication distortions could also be an interesting path [40, 82]. Otherwise, subjectivity must also be considered in the conception and management of work, as people’s affections are always present and there is enormous importance in building and maintaining trust and pertinence, non-material values [84–86]. Therefore, it is necessary to promote the introduction of “sustainable” jobs [87]. There is no neutral work in terms of health, subjective development, and professional issues. There are always positive or negative consequences for workers, for the constitution of collectivities and for society. Positive or negative externalities are always present. It is not enough to give jobs for the population. Work also needs to be sustainable enough to allow people to develop and build health for working populations.

5 Conclusion

In this article we seek to investigate the challenges for a service company (such as a contact center) in reconciling its economic and financial objectives with the promotion of the work dimension, guaranteeing workers the possibility of professional, collective, and human development. The results show that the achievement of economic-financial objectives is mainly done by harming the well-being of its workers. Even if physical working conditions did not present significant risks for people, the work itself did not bring workers’ development. The lack of professional, collective, and human development hinders workers’ well-being and represents a risk to their health. This is especially true in customer service cases typified as “mass service”. In these circumstances, the content of the tasks and the methods of individual evaluation of workers’ performance end up defining production scenarios that are incompatible with the construction of a real profession. The results show that the turnover is so high that there is a complete renewal of the worker population each year. There is no professional perspective and the turnover reflect a kind of “job rejection”.

To reconcile economic-financial objectives with the promotion of the dimension of work, it is proposed that in addition to introducing improvements at a more operational level, more structural changes promoted by work-related sciences such as ergonomics and work psychodynamics need to be implemented. In particular, it was observed that the main cause of the lack of promotion of the work dimension was the presence of asymmetries in power relations. Organizational changes and new rationalities in the decision-making processes of companies are fundamental to improve these scenarios. For this, it is proposed that the work-related sciences connect more with issues that currently have a more strategic reach within organizations, such as corporate sustainability.

Reflecting on the results of the article, it is possible to point out three main research limitations. The first is related to the methodology used in the research. It was possible to analyze the company in detail and therefore reach a reliable diagnosis. However, it was not possible to advance in the phase of the transformation process to implement the diagnostic suggestions. Participating in this phase through an action research [88] would have further enriched the results and the discussion of this research. Another limitation of this study is related to the openness of sustainability departments to embrace concepts derived from work-related sciences in their work within organizations. Although sustainability is recognized as beneficial in economic, social and environmental aspects, in general more emphasis is placed on the latter aspect [89]. In addition, sustainability department still does not have a strong power of action, relying on the efforts of other departments. In the case of matters of the social sphere, the sustainability department generally relies on the results already developed by the human resources department (or similar). The last limitation of this research is the difficulty of convincing companies to change their attitude. In the researched company there were legal pressures to promote improvements in work. However, in companies such as contact centers, there is strong competition to win contracts, mainly focused on contract price. Especially in operations considered to have “low added value”, there are fewer maneuvers to convert benefits for workers into economic and financial gains.
