Holiday can only be taken as it has been accrued, so if your employee takes more time off than they are entitled to for the duration of their employment, you have the right to withhold a portion of their final salary as compensation. Stafftax will help with this calculation.

Statutory entitlement
All employees in the UK are entitled by law to 5.6 weeks holiday per annum.  For a full-time employee that is 28 paid days off per year, of which 4 weeks (20 days) is standard leave and 1.6 weeks (8 days) is all 8 of the bank holidays.

Part-time and temp employment
What about if your employee is only working part-time? The calculation is simple. Multiply the number of days they work by 5.6.

If your employee is employed on a temporary basis they are also entitled to holiday. The calculation of the holiday entitlement for someone in temporary employment in a full-time position is straight forward: divide 28 (the total number of days they would be entitled to if they were working the whole year) with 52 (the total number of weeks in a year). Then you simply multiply the answer with the number of weeks they have been contracted to work.

Example 1: Employee A has been hired to work for Employer B 5 days per week for 16 weeks:

24 / 52 = 0.54 * 16 = 8.6

The holiday entitlement for Employee A is 8.6 days.

If the employee is employed on a part-time basis in a temporary position the calculation is a little bit more complex. First you need to establish the annual entitlement if they were working the whole year. As before, you simply multiply the number of days they work per week by 5.6. Then you follow the steps as outlined in the calculation above.

Example 2: Employee C has been employed to work for Employer D for three days per week for 6 weeks:

5.6 * 3 = 16.8 / 52 = 0.323 * 6 = 1.9

Holiday entitlement for Employee C is 1.9 days.

Pro rata
Pro rata is a word that pops up frequently whenever you're dealing with part-time employment. Just like the salary will be calculated on a pro rata basis so will the holiday entitlement. Pro rata is Latin for "proportionally" or "a proportion of" and it simply means that the part-timer's entitlement is calculated according to what proportion of a full-time job their hours make up.
