As an adult worker, you are entitled to an uninterrupted rest period of not less than 24 hours in each seven-day period. However, if your employer so determines, you are entitled to either two uninterrupted rest periods (each of not less than 24 hours) in each 14-day period, or one uninterrupted rest period of not less than 48 hours in each 14-day period.
The entitlement to weekly rest is in addition to the 11-hour daily rest entitlement that must be provided, except where objective or technical reasons concerning the organisation of work would justify incorporating all or part of that daily rest into the weekly rest period.
Mobile workers in road and rail transport have different rules. They must be given 'adequate rest'. HGV and PSV road transport drivers also have better entitlements through the Road Transport (Working Time) Regulations and the Tachograph Regulations that govern driving hours.
