We have an unlimited holiday policy, however contractually we’ve call this ‘a minimum of 25 days plus bank holidays’. In our policy we talk about ‘if you need more, ask your manager’. We cover this in induction to explain that they would not be able to do their job if they took two weeks a month of. It’s about being an adult and being reasonable (both ways).
Our HRIS is set up for 25 days but employees can exceed their entitlement.
This works well as it gives a number to aim for and also insures people take a decent holiday. Our average is around 28 days. Highest number of days taken in past years 39 days.
It also works for calculating holiday accrual during MAT/PAT leave.
