This document provides clarity on the European Working Time Directive (EWTD) by giving guidance using the views of experts who have already considered most issues arising from the EWTD, implemented in the UK as the Working Time Directive Regulations 1998/the Working Time Regulations (Northern Ireland) 1998 and subsequent amendments. Where a definition already exists by statute or regulation, this is noted; but in other situations a consensus view is given. (Department of Health - publications)
