My company has a policy that if you want to sell back annual leave, it's calculated at 1/260 of annual pay (260 bring the number of working days before holidays/bank holidays are taken).
A couple of people work part time, so think that calculating the monetary value of their annual leave should be 1/208 if you work 4 days/week or 1/156 if you work 3 days a week.
If not considered this before - are they right?
