This report examines the relationship between working time reduction (WTR) and productivity by conducting a systematic review of 75 empirical studies. The objective is to assess whether reductions in working hours can sustain or enhance productivity, and under which conditions. Among the studies reviewed, 45 include an explicit or clearly inferred measure of productivity linked to WTR, this group represents the foundation of the main analytical classification. A further 30 studies provide relevant contextual evidence on mediating factors, such as well-being and work organisation.

This article provides an update of some of the most important aspects of working time regulation in the European Union, including:

• statutory limits on weekly working time
• annual leave entitlements, as set by law and collective agreements
• estimates of average collectively agreed normal working time, including examples in five specific sectors: chemicals, metalworking, banking, retail and public administration.

The most important changes in the regulation of working time in Europe in 2021 and 2022 were related to the transposition of two European directives: the Work–life Balance Directive and the Transparent and Predictable Working Conditions Directive. The reduction of working time and more specifically the four-day working week have been increasingly debated in many EU Member States. In 2022, the average collectively agreed working week in the EU stood at 38.1 hours.

Despite the well-known adverse effects of regular long working hours on workers’ health, well-being and performance, many workers in the EU continue to work beyond their normal hours. Part of this additional working time is classified as overtime. This report takes a comparative overview of how overtime is regulated in the EU Member States, Norway and the United Kingdom, including its definition, the limits on its use and the compensation received by workers for working extra hours.
