I've been employed for 3 years with the same company (it's a charity, but not relevant). My contract states as I'm part time that ' is allowed 15 days holiday (pro rata from 25 days full time) and Bank Holidays. I took that to mean that I could then have ALL the bank holidays plus my holiday entitlement. This is as it's been with my current manager too. They've now left and the new CEO of the charity, thinks that as I'm only part time I should get part time bank holiday entitlement. Where do I stand with this?
