Background: Workers with flexible work designs (FWDs) face specific challenges, such as difficulties in detaching from work, setting boundaries between work and private life, and recovering from work., Objective: This study evaluated the effectiveness of an intervention in improving the recovery, work-life balance, and well-being of workers with FWDs compared with a waitlist control group. It also compares the effectiveness of a web-based training format and blended training format., Methods: In the web-based training format, participants individually completed 6 web-based modules and daily tasks over 6 weeks, learning self-regulation strategies to meet the particular challenges of FWDs. In the blended training format, participants attended 3 group sessions in addition to completing the 6 web-based modules. In a randomized controlled trial, participants were assigned to a web-based intervention group (196/575, 34.1%), blended intervention group (198/575, 34.4%), or waitlist control group (181/575, 31.5%). Study participants self-assessed their levels of primary outcomes (psychological detachment, satisfaction with work-life balance, and well-being) before the intervention, after the intervention, at a 4-week follow-up, and at a 6-month follow-up. The final sample included 373 participants (web-based intervention group: n=107, 28.7%; blended intervention group: n=129, 34.6%; and control group: n=137, 36.7%). Compliance was assessed as a secondary outcome., Results: The results of multilevel analyses were in line with our hypothesis that both training formats would improve psychological detachment, satisfaction with work-life balance, and well-being. We expected blended training to reinforce these effects, but blended training participants did not profit more from the intervention than web-based training participants. However, they reported to have had more social exchange, and blended training participants were more likely to adhere to the training., Conclusions: Both web-based and blended training are effective tools for improving the recovery, work-life balance, and well-being of workers with FWDs. Group sessions can increase the likelihood of participants actively participating in web-based modules and exercises., Trial Registration: German Clinical Trials Register DRKS00032721; https://drks.de/search/en/trial/DRKS00032721., (©Sarah Elena Althammer, Anne Marit Wöhrmann, Alexandra Michel.

This study aimed to investigate the prevalence of three characteristics of work break organization, namely skipping work breaks, interruptions of work breaks, and meal break duration, and their relationships with physical and mental health. We used data from the BAuA-Working Time Survey 2017, a representative workforce survey in Germany, and restricted the sample to 5979 full-time employees. Logistic regression analyses were conducted with in total five health complaints as dependent variables: back pain and low back pain, pain in the neck and shoulder region, general tiredness, faintness, or fatigue, physical exhaustion, and emotional exhaustion. Many employees often skipped their work breaks (29%) and experienced break interruptions (16%). Frequent skipping of work breaks was significantly positively, that is detrimentally, related to all five health complaints and frequent interruptions of work breaks also, except for neck and shoulder pain. Meal break duration was significantly negatively, that is beneficially, related to physical exhaustion., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Strong work-time control (WTC) has been linked to reduced employee exhaustion, with work-to-home interference as an underlying mechanism. In this study, we aimed to investigate the mediation effect of both directions of internal work-home interference, namely internal work-to-home interference (IWHI) and internal home-to-work interference (IHWI). The analysis is based on data from the 2015, 2017, and 2019 BAuA-Working Time Survey, a representative German panel study. Cross-lagged panel models were estimated separately for IWHI and IHWI, based on the balanced panel ( n = 3390). We investigated the hypothesized indirect as well as potential direct, reversed, and reciprocal effects of the constructs. WTC had a small but significant indirect effect on exhaustion via IWHI. Contrary to assumptions, WTC positively affected IHWI. Unexpectedly, there was no significant effect of IHWI on exhaustion. Hence, only IWHI was identified to mediate WTC's effect on exhaustion. This implies that WTC helps employees avoid exhaustion from psychological preoccupation with work during free time. In addition, analyses suggested reversed and reciprocal relationships between the investigated constructs. Further investigation is needed to explore the role of psychological preoccupation with private matters during work time in the context of WTC and employee well-being.

Objective: Due to recent trends such as globalization and digitalization, more and more employees tend to have flexible working time arrangements, including boundaryless working hours. The aim of this study was to investigate the relationships of various aspects of boundaryless working hours (overtime, Sunday work, and extended work availability) with employees' state of recovery. Besides, we examined the mediating and moderating role of recovery experiences (psychological detachment, relaxation, mastery, and control) in these relationships., Methods: We used data from 8586 employees (48% women; average age of 48 years) who took part in the 2017 BAuA-Working Time Survey, a representative study of the German working population. Regression analyses were conducted to test main effects as well as mediation and moderation., Results: Overtime work, Sunday work, and extended work availability were negatively related to state of recovery. Psychological detachment mediated these relationships. Furthermore, we found that relaxation and control mediated the association between extended work availability and state of recovery. However, no relevant moderating effects were found., Conclusions: Altogether, our findings indicate that various aspects of boundaryless working hours pose a risk to employees' state of recovery and that especially psychological detachment is a potential mechanism in these relationships. In addition, the results suggest that a high level of recovery experiences cannot attenuate these negative relationships in leisure time. Therefore, employers and employees alike should try to avoid or minimize boundaryless working hours., (© 2021. The Author(s).)

Health care professionals often face irregular working hours and high work pace. We studied associations of the five working time dimensions duration (weekly working hours), timing (shift work and weekend work), on-call work, working time autonomy, and work tempo (deadline and performance pressure) with well-being among health care employees in Finland and Germany. We used data on working time dimensions and indicators of well-being (work-life conflict, poor perceived health, sleep difficulties, and fatigue) from a cohort of 5050 hospital employees (Working Hours in the Finnish Public Sector Study 2015, WHFPS) and 1450 employees in the health care sector in Germany responding to the German BAuA-Working Time Survey in 2015 (BAuA-WTS). Findings from logistic regression analyses showed that high work tempo was associated with increased work-life conflict (WHFPS: odds ratio [OR] = 3.64, 95%CI 3.04-4.36 and BAuA-WTS: OR = 2.29, 95%CI 1.60-3.27), sleep difficulties (OR = 1.75, 95%CI 1.43-2.15 and OR = 1.33, 95%CI 1.03-1.71) and fatigue (OR = 2.13, 95%CI 1.77-2.57 and OR = 1.64, 95%CI 1.29-2.10) in both datasets. Weekend work was associated with increased work-life conflict (OR = 1.48, 95%CI 1.27-1.72 and OR = 1.61, 95%CI 1.12-2.32); and high working time autonomy with decreased work-life conflict (control over the timing of breaks: OR = 0.65, 95%CI 0.55-0.78 and OR = 0.52, 95%CI 0.33-0.81). The associations between other working time dimensions and well-being were less consistent. These results suggest that tight deadlines, performance pressure, weekend work and lack of working time autonomy are linked to impaired well-being among health care employees.

Career decisions are based on the fit between an individual and his/her environment. This study explores the effect of person-environment fit regarding actual and preferred weekly working hours on early and late retirement intentions in a sample of 7,859 employees aged 50 to 65 years of age living in Germany. Findings from multinomial logistic regression analysis show that a preferred decrease in working hours was associated with an increased risk for early retirement compared to regular retirement intentions (OR = 1.82). A preferred increase in working hours was associated with higher odds for a late career (OR = 1.87).

Working time arrangements that match employees' preferences have been proposed as determinants of employees' well-being, an assumption rooted in person-environment fit theory. The aim of this study was to investigate the role of fit and misfit between actual and preferred working time arrangements (length of working hours, control over the beginning and end of workdays, and workplace segmentation) for employees' satisfaction with work-life balance. We analyzed data from 8,580 employees from the BAuA-working time survey - a representative study among the working population in Germany - by means of polynomial regression and response surface analyses. Analyses did not point toward congruence effects but revealed significant main effects: Satisfaction with work-life balance was higher in case of shorter actual and longer preferred weekly working hours, and it was decreased if employees worked longer than they preferred. Moreover, more supplies and lower preferences in terms of control over the beginning and end of workdays, more workplace segmentation supplies, and lower workplace segmentation preferences were related to higher satisfaction with work-life balance. Overall, this study sheds light on the roles of fit and misfit between actual and preferred working time arrangements for employees' work-home interface. Findings suggest that while employees' preferences should find entrance into the design of work schedules, congruence is not a precondition for achieving a good work-life balance. Most importantly, for a good work-life balance, working hours should not be longer than preferred, and employees should have some control over their scheduling and possibilities to segment work and private life.

This study explores how different aspects of working time demands (e.g., shift work) and working time control (e.g., beginning/end of workday) can be clustered into distinct types of work schedules and how they relate to health and work-life balance. Data from 13,540 full-time employees interviewed in the 2015 BAuA-Working Time Survey was used. By means of latent class analysis, we extracted six types of work schedules. Subjective health was highest in the flexible extended and flexible standard schedules, both featuring high working time control. Work-life balance was highest in the flexible standard and rigid standard schedules and lowest in schedules with high working time demands, namely the extended shift, rigid all-week, and rigid extended schedules. Employees with high working time demands and low control represent risk groups prone to impairments of well-being. Overall, this study offers an intuitive taxonomy for the design of sustainable work schedules., (Copyright © 2019 The Authors. Published by Elsevier Ltd.. All rights reserved.)

The demographic trends (i.e., low birth rates and increasing longevity) pose challenges with regard to the increase of the average employee age along with a lack of skilled personnel on the labor market. Society, organizations, and individuals are confronted with the question on how to prolong working lives in the future. Based on socioemotional selectivity theory, the purpose of this study was to investigate the relationship between respectful leadership and older workers' desired retirement age. In particular, we took a closer look at job satisfaction, subjective health, and work-to-private life conflict as underlying mechanisms. Further, we tested for the moderating role of occupational self-efficacy as an auxiliary condition for the assumed relationships of respectful leadership. We tested our hypothesized model using data from 1,130 blue- and white-collar workers aged 45-65 years. The results of structural equation modeling indicated that respectful leadership was positively related to older workers' desired retirement age and that this relationship was mediated by subjective health and work-to-private life conflict but not by job satisfaction. The findings add to the literature on resources in retirement decision-making; notably, they highlight the importance of leadership behavior for older workers' motivation and socioemotional needs.
