This report examines flexible working arrangements and their effects on working time quality, work–life balance and health, and related regulations. Since 2015, the take-up of flexible working arrangements, accelerated by the pandemic and digitalisation, has increased significantly, with one in five EU workers engaged in telework or having working time autonomy in 2024. Overall, flexible working is associated with improved working time quality and a better work–life balance. However, risks persist, notably irregular schedules, high workloads and work-related contact outside working hours, which strongly undermine health and work–life balance. Regulatory responses, including the recording of working time and the implementation of a right to disconnect, have increased, although unevenly across EU Member States. Despite improvements in the quality of working time, flexible arrangements continue to reveal an evolving organisation of working time, highlighting the need to reassess working time and rest time in an increasingly digitalised world of work.
