I am due to take Mat Leave from August. Where I work every employee is given 4 days off of 'discretionary' leave that have to be taken between Christmas and New Year. I have been told I won't be entitled to these whilst on maternity leave, I had been expecting to add them to my annual leave entitlement. This feels wrong and discriminatory as if I wasn't on Mat Leave I would be entitled to them? Its the equivalent of a weeks pay to lose, so I want to make sure I don't lose it if they are wrong (its a small company with limited HR experience). Any help much appreciated.
