Thanks Ruthiu and Kevin, more useful information and links.
on another issue if an employee does not take there annual leave by the end of a holiday period what is the legal stance an employer should take, I understand there are theee options:
1. Pay them holiday pay as an additional paymenot, which I believe is not strictly legal as this would discourage employees from taking leave,
2. Employee loses their entitlement to their accrued leave as they have not taken it, not sure on any legal stance fir this, or
3, leave is rolled over to the following year.
Thanks once again
