How to refuse to do unpaid overtime

The TUC (Trades Union Congress) in Britain released a report today revealing that single women in their 30s doe more unpaid overtime than anyone else.

Single women in every age group are more likely to do unpaid overtime than single men in the same age group, but 39% of single women in their 30s do unpaid overtime, compared to 26% of men in their 30s.

The TUC recommends that today ("Work Your Proper Hours Day") employees should take a proper lunch break and leave work on time. They also recommend Britain's employers to say thank you for all the extra work by taking their employees to lunch!

However, if you need to let your boss know that you can't (or won't) work overtime, try these phrases:

I can't work late tonight.
I'm afraid I have other commitments this evening.
I have family commitments this weekend.
I need to leave work on time today.
