Abstract This chapter considers the different types of rest for which provision is made under the Working Time Regulations 1998 (WTR): rest breaks, daily rest and weekly rest. The particular categories of workers who are excluded from the entitlements to rest are outlined. The difficult issue of rest for on-call workers is discussed, as is the scope of the duty on an employer to enforce the taking of rest by workers. The chapter concludes by looking at record-keeping, enforcement, and the remedies for breach of a worker’s entitlement to rest.
