Working Time Opt-Out

A working time opt-out is a voluntary, written agreement in which a worker agrees that a maximum-hours limit does not apply to them. It is best known from the UK, where an adult worker can opt out of the average 48-hour weekly limit.

How it works

• It must be voluntary and in writing; a worker cannot be forced or penalised for refusing.
• The worker can cancel it with notice (at least seven days in the UK, up to three months by agreement).
• It waives the weekly average limit, not rest breaks or other protections, and does not exist in every country.

Why it matters

An opt-out changes how the weekly limit applies, so employers must keep clear records of who has signed and the hours they work.
