Question: what is the formula for working out annual leave?
Answer: The basic way to work out how many days holiday an employee is entitled to is to multiply the number of days a week they work by 5.6. That gives someone working a five-day week the 28 days we've already mentioned. Someone who is part-time and only works three days a week would be entitled to 3 x 5.6 = 16.8 days.
