I'm just wondering about this for my dad.
He works part time, 3 days a week. His employer has worked out that he should get 17 days annual leave. I'm assuming this is 20 + 8 (bank holidays), reduced to reflect 3 days work instead of 5.
However, his employer is making him include his normal days off as annual leave, if they fall between days off. For example. His normal working days are Wed-Fri. He went on holiday from Friday to Wednesday and they recorded that as four days annual leave (Friday, Monday, Tuesday and Wednesday). This doesn't sound right to me. Should it be two days?
