Compensatory rest28
Where the application of any provision of these Regulations is excluded by regulation 25 or 26, or is modified or excluded by means of a collective agreement or a workforce agreement under regulation 27(a), and a worker is accordingly required by the employer to work during a period which would otherwise be a rest period or rest break—
a
the employer shall wherever possible allow the worker to take an equivalent period of compensatory rest, and

in exceptional cases in which it is not possible, for objective reasons, to grant such a period of rest, the employer shall afford the worker such protection as may be appropriate in order to safeguard the worker's health and safety.
