Yes, in most cases an adult worker is entitled to a rest period of at least 11 consecutive hours in each 24-hour period. However, this entitlement is subject to the following exceptions:
(a) where working time is 'unmeasured' - this basically means that the duration of working time is not measured or predetermined or can be determined by the worker himself. Therefore, if you have complete control over your hours and the time is not monitored or determined by the employer, you fall within the exception.
(b) where the worker is engaged in one of the 'special case' activities - this includes various sectors (air, rail, road, sea..etc) and the activities of doctors in training.
(c) where a shift worker changes shify and cannot take the daily rest period between the end of one shift and the start of the next one
(d) where the worker is engaged in activities involving periods of work split up over the day (eg cleaning staff)
(e) where the right is modified or excluded by a collective or workforce agreement
However, where one of the above exceptions apply, the employer must allow the worker to take an equivalent period of compensatory rest and, in exceptional cases where this is not possible for objective reasons, the employer must afford the worker such protection as may be appropriate in order to safeguard the worker's health and safety.
