Virtual teamwork as a new way of working is becoming increasingly prevalent in a growingly globalized and digitalized working environment. Due to the associated raise in health-related stress factors at the workplace and the central role of leaders in workplace health promotion, the aim of this study is to obtain initial findings on the use of health-oriented self- and employee leadership in virtual teams from the perspective of virtual leaders. Semi-structured telephone interviews were conducted with 13 virtual leaders by using the problem-centered interview method. The collected data were deductively and inductively evaluated and interpreted using the qualitative content analysis according to Mayring. The results show that virtual leaders ascribed great value of health and showed great awareness in health-oriented self- and employee leadership. Physical activity and boundary management were particularly mentioned as health-oriented self-leadership behaviors. The majority of leaders described communication, building trust, support in boundary management and implementation of personal meetings as health-oriented employee leadership behaviors. In addition to social, technical, and personal factors, primarily organizational factors were mentioned as factors of influence in this context. For a more comprehensive understanding of health-oriented leadership, the inclusion of virtual team members in further research studies is necessary.

Background: The significant increase of digital collaboration, driven by the current COVID-19 pandemic, is resulting in changes in working conditions and associated changes in the stress-strain perception of employees. Due to the evident leadership influence on employees' health and well-being in traditional work settings, there is a need to investigate leadership in virtual remote work contexts as well. The objective of this scoping review was to assess the extent and type of evidence concerning virtual leadership in relation to employees' mental health, job satisfaction and perceptions of isolation.Method: A search was undertaken in five databases, PubMed, Cochrane Library, PsycINFO, PSYNDEX and Web of Science, as well as reference lists of included articles on 9th February 2021 and an update on 28th September 2021. The search strategy was limited to English, German and French language, peer reviewed journal articles published from January 2000 onwards. This scoping review was conducted in accordance with the JBI methodology for scoping reviews. The methodological quality of the included studies was assessed using the JBI critical appraisal tools. A narrative synthesis was conducted.Results: Nineteen studies met the eligibility criteria for this review. Overarching review findings suggested a positive link between virtual leadership and well-being, job satisfaction, and a negative link to psychological strain, stress and perceptions of isolation of digitally collaborating employees.Conclusions: By mapping the available evidence on virtual leadership in relation to health and work-related employee outcomes, the review identified many research gaps in terms of content and methodology. Due to limited data, causal relationships were not derived. Future research is needed to examine the complex cause-and-effect relationships of virtual leadership in more detail.

Background: Health-oriented leadership (HoL) has a positive impact on health- and work-related outcomes of employees in face-to-face settings. Increased digitization during the COVID-19 pandemic has led to many changes and increased job demands. According to current state of research, HoL in virtual teamwork is insufficiently researched. The aim of the study is to examine the experiences of virtual leaders during the COVID-19 pandemic and to identify preconditions and preventive measures for promoting HoL. Method: Using a qualitative study design, semi-structured, guide-based telephone interviews were conducted with 16 German virtual leaders between May and July 2021. The collected data were inductively analyzed and interpreted using qualitative content analysis according to Mayring. Explorative analyses of differences between leaders with and without pre-pandemic experiences with virtual leadership were made. Results: Results indicated that leaders, regardless of pre-pandemic experiences with virtual leadership, faced diverse challenges in implementing HoL in virtual teamwork during the COVID-19 pandemic. Virtual leaders perceived personal preconditions (e.g., leaders’ characteristics or behaviors), organizational preconditions (support by management or open-minded corporate culture), social preconditions (e.g., social support by team) and technical preconditions (e.g., sufficient technical equipment) as conducive to implementation of HoL. Almost all leaders with pre-pandemic experience identified a need for structural preventive measures, whereas almost all leaders without pre-pandemic experience reported a need for behavioral preventive measures in order to promote HoL in virtual teams. Conclusions: This study suggests that implementing HoL in virtual teamwork is challenging, complex and requires adjustments in leadership behavior. Thereby, the study provides initial empirical findings for a holistic approach to HoL implementation in virtual teams, considering beneficial multilevel preconditions. Due to a limited generalization of present results, longitudinal and interventional studies will be necessary for the analysis of causal relationships in future research. In particular, a holistic research perspective in order to understand the complex, contextual interdependencies of leadership is recommended. In practice, based on a differentiated needs analysis, structural preventive measures for a holistic organizational development as well as behavioral preventive measures for ongoing personnel development are recommended.

Social firms are located on the general labor market and employ 30–50% of severely disabled people. Findings on personal and work-related impacts for employees and supervisors during the COVID-19 pandemic are not yet available and will be investigated in the present study. Using the approach of a method triangulation, focus groups with employees and individual interviews with supervisors of several social firms from the North of Germany were combined and collected in parallel. Between July and November 2020, 16 semi-structured telephone interviews with supervisors and three focus groups with 3–6 employees each working within the same team (14 employees in total) were conducted. Both formats were recorded, transcribed, anonymized, and analyzed by using Mayring’s qualitative content analysis. Because a large proportion of the employees and supervisors interviewed worked in the gastronomy sector, they were particularly affected by the “restriction of social contacts” beginning in March 2020. Hygiene and distance regulations were implemented and personnel planning and distribution of work were adapted. Challenges were raised for employees with disabilities due to the implementation of hygiene and distance regulations, a sudden loss of work, lacking routines, additional work, a lack of movement, social contacts and financial challenges. Both employees and supervisors reported fears of infection, conflicts, additional work and fears of job loss. Additionally, supervisors dealt with less staffing, challenges in detaching from work and a strained economic situation. Overall, new insights were gained into the work-related impacts for employees and supervisors in inclusive workplaces during the current COVID-19 pandemic but further research on health-promoting structures is needed.

Background: Social firms – a type of social enterprise – provide job opportunities to people with mental or intellectual, sensory, physical or multiple disabilities who are disadvantaged on the general labour market. Given the limited number of studies on working conditions of employees in inclusive workplaces, the aim of this study was to explore job demands and resources experienced by employees with disabilities in German social firms. Methods: Three focus groups were conducted between September and October 2020 with 14 employees with disabilities from social firms in the catering and cleaning sector in Germany. The Job Demands-Resources model was used as a theoretical basis for developing the semi-structured interview guide. Audiotaped data were transcribed verbatim, analysed deductively and inductively using the qualitative content analysis according to Mayring. Results: The results show that employees of social firms experience specific job demands and resources regarding work content, work organisation, social relations and work environment. Job demands were mainly reported with respect to work organisation, e.g. high workload, time pressure or challenges in collaboration, whereas social relationships with colleagues and supervisors were most frequently mentioned as important resources at the workplace. Conclusion: First exploratory study results on the working conditions of employees in social firms in Germany were obtained. Given the pivotal importance of employment for people with disabilities, the identified job demands and resources of this study highlight the relevance of a healthy workplace, especially for employees in social firms. Future interventional research is needed regarding the development, implementation and evaluation of workplace health promotion measures in social firms.

On the general labor market, social firms provide 30–50% of people with different types of disabilities the opportunity to gain employment. However, the topic of workplace health promotion (WHP), needs for improvement and accompanied challenges are neglected in the current research and were the focus of the present study. Therefore, data triangulation was used between July and December 2020 by combining three focus groups with employees (n = 14 employees) with 16 interviews with supervisors from several social firms in Northern Germany (e.g., from catering, cleaning or bicycle repair sectors). 17 semi-structured telephone interviews with experts in the field of WHP or social firms were added. All approaches were audio-taped, transcribed and anonymized. To analyze the data, Mayring’s qualitative content analysis was used. The results indicated that several offers for WHP, including sport, nutrition and relaxation, were offered, as well as those on smoking cessation, cooperation with external organizations or training and education offers. Needs for improvement were stated referring to additional sport offers, support for implementing a healthy diet, offers for relaxation, financial incentives or collaborations with external organizations. A low take-up of offers; a lack of resources, structures or management support; compatibility of offers with work time and organization; challenges with available trainings or the consideration of individual needs and capacities were highlighted as challenges. Overall, there is a need for further interventional and longitudinal research on WHP in social firms.
