There’s a quick and simple trick for working out an employee’s pro rata holiday. Multiply the number of days they work each week by 5.6. If a pro rata employee works 3 days a week, then their holiday entitlement is 3 x 5.6, or 16.8 days. Obviously, giving staff 0.8 of a holiday is awkward, for timekeeping purposes and the employee. It’s usually worth rounding this up to the nearest whole number, 17 in this case. Well, the basic statutory holiday entitlement of a full-time employee is 28 days. Five, multiplied by 5.6, gives us the full 28 days’ entitlement.Īnother important element to consider when employing someone on a pro-rata basis is benefits.
