In recent years, work engagement has been attracting attention as a concept that focuses on the positive psychological aspects of workers. In this study, we examined whether writing and reading aloud positive events that take place in the workplace would be useful as a measure to improve work engagement and to reduce occupational stress among care workers in such facilities.</p><p><strong>Methods: </strong>Participants included 57 care workers (across 13 groups) working at seven welfare facilities in Wakayama Prefecture, Japan. A crossover trial with two groups the intervention and control groups was used. The intervention group wrote about positive events, and read them aloud for each group at the morning assemblies and other gatherings. The control group continued work as usual. The survey spanned eight weeks. The questionnaire items were sourced from the Japanese version of the Utrecht Work Engagement Scale (UWES), the Brief Job Stress Questionnaire (BJSQ), and included items concerning participants' biographical attributes. The number of positive events that the participants individually wrote about and the frequency of listening to reading about them was asked for at the end of the intervention period. Multiple linear regression analysis was used to examine the relationship between the number of written accounts or the frequency of listening to readings and the amount of change in the scores of the subscales.</p><p><strong>Results: </strong>The median number of positive events that the participants individually wrote about was three (interquartile range 1-5). The number of those who answered that the frequency of listening to readings was rare was 22 (38.6%).

However, the association between SJL and presenteeism among workers in Japan remains unclear. This study aimed to verify the following hypotheses in a sample of workers in an industrial setting in Japan: \"Workers exhibiting SJL have a high degree of work functioning impairment due to presenteeism\" and \"An association between SJL and presenteeism exists, even when taking work style and sleep-related factor into consideration.\"</p><p><strong>Methods: </strong>A self-administered questionnaire survey was conducted with 1,573 workers in the manufacturing industry.
