Working hours in the UK are governed by the Working Time Regulations 1998. These limit the working week to an average of 48 hours (although there is an opt-out), and the working day to an average of 8 hours. They also give workers and employees the right to paid leave and specified rest breaks. Here you'll find resources giving the basics, Q&As on specific issues, and relevant case law. There's also a separate set of Q&As on managing leave for reservists in the armed forces.
