Your rights at work
What are the rules about hours of work?
In most jobs, your employer can say you have to work 8 hours a day. If your employer's regular work day is more than 8 hours, they can say you have to work the number of hours in their regular work day. But, in most jobs, the regular work day cannot be more than 13 hours. And the regular work week cannot be more than 48 hours.
The rules about hours of work may not apply to you if you agreed in writing to different rules. If you are protected by a union, the union can make an agreement with your employer about hours of work.
