Can an adult worker work more than the limit imposed by the Working Time Regulations 1998?

An adult worker may agree to work more than an average of 48 hours a week so long as he or she does so voluntarily and in writing without any pressure from the employer. The opt-out agreement may relate to a specific period or apply indefinitely. Subject to any provision in the agreement providing for a different period of notice, it will be terminable by the worker giving not less than seven days' written notice to the employer. Where a different period of notice is agreed this should not exceed three months. A worker cannot be penalised, victimised, disciplined, dismissed, selected for redundancy or subjected to any other detriment for refusing to sign an agreement opting out of the 48-hour week.
