There are two calculations to do to work out the annual holiday payments for these employees:
1. The employee is paid for any remaining annual holidays that they are entitled to. These are paid at the rate of the greater of ordinary weekly pay or average weekly earnings, as if the holidays were being taken at the end of the employment, and
2. the employee also gets an annual holiday payment of 8% of their gross earnings. Gross earnings:
are calculated from the date the employee last became entitled to annual holidays ie since their last anniversary date for annual holidays & include other payments made in the final pay.
