Arbeitszeitgesetz
Working hours in the UK are currently not limited by day, but by week, as first set by the Working Time Regulations of 1998, which introduced a limit of 40 hours per week for workers under 18, and 48 hours per week for over 18s. This was in line with the European Commission Working Time Directive of 1993. UK regulations now follow the EC Working Time Directive of 2003, but workers can voluntarily opt out of the 48 hour limit. A general 8 hour limit to the working day has never been achieved in the UK. By the end of the 20th century, many people considered them selves to be "money-rich, time-poor".
