The aim of this metaanalysis is to investigate to what extent vacation has positive effects on health and well-being, how long such effects endure after work resumption, and how specific vacation activities and experiences affect these relationships. Methods: Based on a systematic l i t e r a t u r e s e a r c h ( P s y c I n f o , M e d l i n e ) a n d methodological exclusion criteria, in a stepwise approach, 7 studies were selected and reviewed. Effect sizes (Cohen's d) were calculated i) for every outcome variable within every study, ii) for every study by averaging the effect sizes per study, and iii) for homogeneous categories of outcome variables (exhaustion, health complaints, life satisfaction). Results:The results suggest that vacation has positive effects on health and well-being (small effect, d=+0.43), but that these effects soon fade out after work resumption (small effect, d=-0.38). Our research further demonstrated that vacation activities and experiences have hardly been studied. Therefore, their contribution to vacation effect and fade out remains unclear. Discussion: Progress in future vacation research will depend on strong research designs that incorporate repeated measurements pre-, inter-and post-vacation. (J Occup Health 2009; 51: 13-25)

In recent years, there has been heightened interest in the active role of employees in shaping activities and experiences in their pursuit of optimal functioning (i.e., feeling and performing well), referred to as job-, leisure-, home-, and work-life balance crafting. Various perspectives have emphasized distinct dimensions within the crafting process (i.e., motives, behaviors, life domains, and outcomes) yielding a rich but fragmented theoretical account. With psychological needs satisfaction as the underlying process, we propose an integrative model to account for past conceptualizations of crafting motives and efforts across a person´s various role identities. This integration highlights the importance of recognizing unfulfilled needs, matching needs and crafting efforts, within-and between-level temporal dynamics of the crafting process, and possibilities for spillover and compensation processes across identity domains. Accordingly, the Integrative Needs Model of Crafting explains a) why and how people craft, b) when and why crafting efforts may (not) be effective in achieving optimal functioning, c) the sequential process of crafting over time, and d) how crafting processes unfold across different identity domains.

Only few studies so far have examined recovery from work during workday breaks. In this intervention study, based on the effort-recovery model and the conservation of resources theory, we examined how to enhance recovery during lunch breaks. More specifically, we examined the within-person effects of lunchtime park walks and relaxation exercises on employees’ levels of concentration, strain, and fatigue experienced at the end of a working day. We moreover tested whether detachment from work and enjoyment experienced during lunch breaks transmitted the effects of these activities to well-being outcomes. Participants in the park walk (n = 51) and relaxation (n = 46) groups were asked to complete a 15-min exercise during their lunch break on 10 consecutive working days. Afternoon well-being, lunchtime detachment, and lunchtime enjoyment were assessed twice a week before, during, and after the intervention, altogether for 5 weeks. Multilevel analysis results showed that park walks at lunchtime were related to better concentration and less fatigue in the afternoon through enjoyment. Relaxation exercises were related to better concentration in the afternoon via detachment. In addition, relaxation exercises were directly linked to lower levels of strain and fatigue in the afternoon. Our study suggests that on days on which employees engage in recovering activities during lunch breaks, they experience higher levels of well-being at the end of a working day. These results add to the theory-based knowledge on recovery during workday breaks and highlight the importance of breaks for organizational practices.

Most vacations seem to have strong, but rather short-lived effects on health and well-being (H&W). However, the recovery-potential of relatively long vacations and the underlying processes have been disregarded. Therefore, our study focused on vacations longer than 14 days and on the psychological processes associated with such a long respite from work. In the present study, we investigated (1) how health and well-being (H&W) develop during and after a long summer vacation, (2) whether changes in H&W during and after vacation relate to vacation activities and experiences and (3) whether changes in H&W during and after vacation relate to sleep. Fifty-four employees reported their H&W before, three or four times during and five times after vacation. Vacations lasted 23 days on average. Information on vacation experiences, work-related activities and sleep was collected during vacation. Vacation activities were assessed immediately after vacation. H&W increased quickly during vacation, peaked on the eighth vacation day and had rapidly returned to baseline level within the first week of work resumption. Vacation duration and most vacation activities were only weakly associated with H&W changes during and after vacation. Engagement in passive activities, savoring, pleasure derived from activities, relaxation, control and sleep showed strong relations with improved H&W during and to a lesser degree after vacation. In conclusion, H&W improved during long summer vacations, but this positive effect was short-lived. Vacation experiences, especially pleasure, relaxation, savoring and control, seem to be especially important for the strength and persistence of vacation (after-) effects.

The current study investigates the benefits of a good night's sleep and short work breaks for employees' daily work engagement. It is hypothesized that sleep and self-initiated short breaks help restore energetic and self-regulatory resources which, in turn, enable employees to experience high work engagement. A daily diary study was conducted with 107 employees who provided data twice a day (before lunch and after work) over five work days (453 days in total). Multilevel regression analyses showed that sleep quality and short breaks were beneficial for employees' daily work engagement. After nights employees slept better, they indicated higher work engagement during the day. Moreover, taking self-initiated short breaks from work in the afternoon boosted daily work engagement, while taking short breaks in the morning failed to predict daily work engagement. Taking short breaks did not compensate for impaired sleep with regard to daily work engagement. Overall, these findings suggest that recovery before and during work can foster employees' daily work engagement.
