A ground-breaking international survey of cleaners, commissioned by UNI Global Union, sheds light on the significant challenges faced by cleaning professionals who work irregular and unsocial shifts. The survey, which received responses from over 2,500 cleaners in 32 countries across 6 continents, highlights the detrimental effects of nighttime on the health, well-being, and social inclusion of workers. 

The results of the survey indicate that cleaners who work shifts other than the day shift experience a range of adverse effects on their lives. These effects include isolation, difficulties in maintaining relationships, strained social lives, poor sleep schedules, exhaustion, and adverse impacts on physical and mental health.
