The working time directive rules maximum weekly working hours. Find out how to calculate weekly working hours and hourly time limits for young workers.
AVERAGE WORKING HOURS: As a rule, most UK workers cannot work longer than 48 hours a week - as an average.
That means your working hours will get averaged out over a period of 17 weeks. This is according to a list of employment laws and legislation in the United Kingdom.
Employers call it the 'Working Time Regulations' (WTR) or the 'working time directive'.
Even so, many workers choose to work more than the 48 hour work week. They do so by opting out of the standard 48-hour week.
Note: Young workers under the age of 18 cannot opt out of the 48 hour work week. Thus, they cannot work more than eight (8) hours a day or forty (40) hours per week.
Workers in certain types of jobs or professions may work more than the 48 hours a week average. Commonplace examples where the working week is not covered by the Working Time Regulations would include:

As a rule, employers use a 'reference period' for calculating average working hours. In most cases, the reference period will be seventeen (17) weeks. Thus, workers can work more than 48 hours in any given week providing it averages less than 48 hours a week for the 17 weeks.
Note: Workers under the age of 18 cannot have their working hours averaged out. That means young workers cannot work more than forty (40) hours in any given week.

You must be at least 18 years old to work more than 48 hours a week - as an average. Doing so means you would be 'opting out' of the Working Time Regulations 48 hour limit.
I [insert your name here] agree that I may work for more than an average of 48 hours a week. If I change my mind, I will give my employer [insert the amount of time here (which can be up to three (3) months)] notice in writing to end this agreement.
Employers can ask some of their workforce (but not all) to opt out. But, workers cannot get dismissed from work or treated 'unfairly' (disadvantaged) if they refuse to accept it.
Note: Workers can either opt out for a certain period of time or without any defined period. Even so, opting out must be voluntary and stated in writing.
There are certain types of workers that cannot opt-out of the 48 hour work week, such as:
You need to give your employer advanced notice to cancel your 48 hour opt out agreement. As a rule, the notice period will be at least seven (7) days and up to three (3) months.
Note: The Working Time Regulations do not allow employers to force any of their workforce to cancel their opt-out agreement.
