By default, I would always say yes. Aside from the legality, it's a sure fire way to make someone absent from your organisation feel unwanted, if you tell them they've not been any part of your organisation's success in the last 12 months.

In reply to Nina Waters:

Hi Lisa

Agree with Nina and re the legality: were a discretionary’ bonus be paid to colleagues not on maternity leave and withheld from a a woman just because she was away on maternity leave then that’s going to be unlawful specifically and probably discriminatory too. It’s less clear cut hypothetically with actual sickness but any withholding associated with an Equality Act disability might be discriminatory too and often determining whether it is or not might be almost impossible.
