This study aimed to analyze the scientific evidence available in the literature addressing the relationship between mental fatigue and burnout associated with teleworking during the COVID-19 pandemic through an integrative review. This review searched the following databases: PubMed, Scopus, Taylor & Francis, Embase, ScienceDirect, and SciELO using the DeCS and MeSH health sciences descriptors. The included articles were published between March and December 2021, during the pandemic. Of a total of 224 results, 215 articles were excluded and 9 were considered for the preparation of this integrative review. Mental fatigue was related to technostress, somatic symptoms such as anxiety and insomnia (p < 0.05), and loss of motivation (p < 0.05). Burnout was positively associated with work overload, high interdependence, and lower role clarity. The presence of a stressful factor and a protective factor was evidenced in burnout: intrusive leadership and workaholism, respectively. Greater exhaustion was observed in workers belonging to generation X (41 to 55 years old). Mental fatigue is related to exhaustion in the productive, physical, and psychological dimensions of individuals. Addiction to work has moderated this phenomenon, however, it is urgent to limit and optimize work hours as well as promote disconnection and rest among workers within the framework of a healthy work policy.

Keywords: professional burnout; teleworking; occupational diseases; occupational health.


Este estudo pretendeu analisar as evidências científicas disponíveis na literatura sobre a relação entre fadiga mental e esgotamento associados ao teletrabalho em tempos de pandemia de covid-19 mediante uma revisão integrativa. Esta revisão incluiu a pesquisa nos seguintes bancos de dados: PubMed, Scopus, Taylor & Francis, Embase, Science Direct e SciELO. Usando os descritores DeCs e MeSH de ciências da saúde, os artigos incluídos foram datados entre março e dezembro de 2021, durante a pandemia. De um total de 224 resultados, 215 artigos foram excluídos, e 9 foram considerados para a elaboração desta revisão integrativa. A fadiga mental foi relacionada ao tecnoestresse, à presença de sintomas somáticos, como ansiedade e insônia (p < 0,05) e à perda de motivação (p < 0,05). O esgotamento foi positivamente associada à sobrecarga, alta interdependência e falta de clareza quanto à função do trabalhador. Evidenciou-se a presença de um fator estressante e de um fator protetor em relação ao esgotamento, como a liderança intrusiva e o vício no trabalho, respectivamente. Observou-se maior exaustão nos trabalhadores da geração X (41 a 55 anos). Concluiu-se que a fadiga mental está relacionada à exaustão nas dimensões produtiva, física e psicológica dos sujeitos. A dependência do trabalho moderou esse fenômeno, porém, é urgente limitar e otimizar as horas de trabalho, bem como promover a desconexão e o descanso dos trabalhadores no âmbito de uma política de trabalho saudável.

During the COVID-19 pandemic, the online, telecommuting, and home-based work modalities were intensified for different types of work around the world in order to limit productive unemployment, adapt the operation of companies, and limit contagion. This was a complex health scenario with a very high demand for health care centers.1 Remote workers were approximately 40% in Canada,2 71% in the United States,3 60% in Nordic countries, and 37% in the European Union.4 Considering this work system, research has been emphatic in rescuing the positive aspects of this modality. Working from home provides greater flexibility, productivity, efficiency, and satisfaction.5 In this sense, this form of teleworking also saves commuting time and promotes faster work, mainly for workers who require greater concentration in solving complex problems, provided that the home office protects the worker from elements such as unexpected visits and constant distractions.6

On the other hand, and the issue addressed by this review, the telework system also brings forth negative elements, mainly in jobs that require interaction and collaboration with others. Executing tasks from one’s home becomes more difficult and slower due to social and professional isolation; the instances in which information is shared and cultivated are lacking. These links increase trust in work teams.7 The rapid adaptation to the online reality to which workers have been exposed has been compensated by excessive interaction and demand for time invested in connectivity,8 as well as a minimal separation between work and personal environments.9 This aspect is related to the constant disturbance and interruption of workspaces due to the need to also attend to domestic and family situations.10

Studies warn that stressors mentioned in remote jobs may be associated with a harmful overload reported by workers in different areas, characterized by the presence of fatigue, weariness, exhaustion, and somatization of signs and symptoms such as pain, increased anxiety, and sleep disorders.11

On the other hand, reports of negative elements associated with teleworking constitute an alert for creating new guidelines and redesigning this work modality to mitigate the associated risks and protect healthy working conditions that are in greater harmony with the human being.12 Recognizing the scope of these issues will allow us to address the most critical aspects that require adjustments to improve working conditions in the teleworking modality. The foregoing may play a moderating role in the regulatory frameworks designed for this work system, which may continue after the pandemic.

The purpose of this review is to explore the interactions between fatigue and burnout syndrome in teleworkers at different jobs and integrate the results found on this matter.




This integrative review work was based on evidence of previous studies from the following stages: a) formulation of a research question; b) literature search; c) data collection; d) critical analysis of the included studies; e) summary of the main results; and f) presentation of the integrative review.

The following question was posed to guide our research: What is the relationship between mental fatigue and burnout syndrome due to home-based work or teleworking in different jobs during the pandemic?

The researchers used the PICO method (P: patient/problem; I: intervention; C: comparison; O: result/outcomes) to search for articles in the selected databases.


The search was carried out in the PubMed, Scopus, ScienceDirect, Taylor & Francis, Embase, and SciELO databases considering articles published between March and December 2021 in both Spanish and English. The search was performed using the Medical Subject Headings (MeSH) and Health Sciences (DeCs) thesaurus descriptors related to the objective of the review, linked with Boolean operators (AND) and (OR). The concepts included were “fatigue,” “mental,” “exhaustion,” “home,” “office,” “telework,” “remote work,” and “pandemic.”

Study selection was initially performed by reading the titles and abstracts. This phase also made it possible to eliminate articles that presented at least one exclusion criterion. In a second phase, the included articles were reviewed to ensure that they met all the inclusion criteria.

The inclusion criteria consisted of only original observational research papers and reviews that included the study of mental fatigue and burnout associated with teleworking during the pandemic, published between January and December 2021, available in English or Spanish.

The exclusion criteria consisted of studies that did not include at least three of the keywords in the title, case studies, book chapters, and conference papers. Articles published in years other than 2021 and in languages other than English and Spanish were also excluded.

Potentially relevant articles were reviewed by the researcher and an external researcher to determine their completeness. Discrepancies between the two researchers were resolved by a third author who acted as expert judgement.


The data extraction process was carried out by the researcher using a Microsoft Excel file detailing the author, year of publication, type of study and journal, design and sample size, prevalence of mental fatigue and burnout, and recommendations to the job. The methodological rigor of the studies was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) Methodology Checklist tool. Only articles that reached the “high quality (++)” and “acceptable (+)” categories were included.



After the search, 224 articles were found in the identification phase using the descriptor. In the selection stage, articles were excluded based on their unrelated titles and duplication. The eligibility criteria (by abstract and full text) led to nine articles that were finally included and analyzed (Figure 1).

The results of this analysis are shown in Table 1, which shows the main authors, titles, journals, objectives, main results, and future suggestions for the work according to the authors.




After analyzing the articles included in this review, risk factors and stressors associated with teleworking become evident. Nevertheless, protective and moderating factors of work overload in a virtual environment were also observed.

The first stressor corresponds to what is evidenced in the work of Spieler & Baum,13 who warn that the overexposure to computer screens for much of the day has been related to tiring effects on attention, concentration, and visual fatigue for different groups, ages, and genders.22 On the other hand, static postural overload was related to body pain and muscle tension.23,24

Another criterion includes technostress and technological difficulties linked to connection problems, platform management, and incompetence to deal with Information and Communications Technology (ICT), found by Bonanomi et al.21 and Ghasemi et al.14 This has been related to a greater demand for time invested in solving technical problems, which delays the progress of work tasks and was linked to greater anxiety and cognitive irritation.25-27

Regarding the work environment of Martínez et al.19 and Mihalca et al.,18 intrusive leadership and over-hours contributed negatively to worker performance and led to stress, insomnia, depression signs and symptoms, loss of motivation, mental exhaustion, depersonalization, and increased need for psychological or psychiatric care.28

Although teleworking has had negative effects, aspects that would act as protectors against overload have been described, mitigating and buffering the mental workload; these include workaholism and recognition of the company towards its workers,29 being in line with the results found by Magnavita et al.20

Additionally, studies by Barbieri et al.17 reported that women had lower self-efficacy and job satisfaction when having to solve domestic problems and caring for preschool children. In this sense, women have experienced the overload of reconciling work, domestic, family, and parenting activities.30

To mitigate and counteract the effects described as detrimental to occupational health, various initiatives derived from studies and research aim to make adjustments that address both work systems and good employer practices.31,32

Among the suggestions proposed by the authors,13,14,17,18 those focused on work systems aim to: a) manage workers’ self-assessment early, allowing them to recognize exhaustion and intervene promptly; b) limit distractions and shorten work times by improving efficiency; c) provide brief training in the use of technology and simultaneous support for problem-solving; d) improve the identification of workers’ skills to redesign roles, tasks, and promote autonomy.

On the other hand, proposals related to the companies’ good practices16,20,21 suggest: a) increasing the duration of rest times associated with the systematic guided practice of mindfulness or meditation; b) providing the assistance of professional psychologists for their workers; c) preventing work addiction and promoting disconnection through free time.

Recent studies suggest reviewing the impact that the creation of new telecommuting jobs could have and improving the separation between work and non-work domains to mitigate the negative effects related to exhaustion, mental fatigue, and tiredness by overload.33

Another important recommendation is to review the correlation between the frequency and duration of calls and videoconferences per working day with the mental processes that mediate these activities such as attention and concentration, as well as production processes through performance.34 The foregoing will make it possible to estimate whether reducing the number of calls and/or online time during teleworking is feasible.


The limitations of this work are mainly the heterogeneity of the primary studies and those included in the review. Second, the lack of new studies from the citation and/or organization search, which is why the final number of included studies was low.



Although working from home rescues positive aspects in times of a pandemic, this work allows us to visualize and conclude that the organizational conditions of work have deteriorated and there is real exposure to stressors that harm the mental, productive, and physical dimensions of individuals. It is necessary to review the maturity and critical awareness of the exposure of workers to the immediacy and to examine suggestive surveillance tools such as telepressure via control devices in contexts of overload.

In this sense, we should reflect and promote research that includes a greater homogenization of studies to allow better comparisons, evaluate the differences between men and women who, as evidenced, assimilate stressors differently and have different moderating and/or protective mechanisms.

Along this line, incorporating works that evaluate pre- and post-intervention measures could also allow discussing the efficiency of resources and strategies used to reduce the negative effects of teleworking.
