There are special case exceptions, including where the worker’s activities involve the need for continuity of service or production (regulation 21, WTR). This covers sectors such as hospitals, agriculture, retail trading, hotels and catering businesses, bakeries, fisheries, and postal and newspaper deliveries, which are exempted from the night working restrictions because of their particular operational needs. Work in bars and restaurants is also exempted. The eight-hour limit can also be modified by a workforce agreement. In all these cases, there must be compensatory rest (regulation 24, WTR) (see page 179).
