What are part-time workers' rights to paid holiday?

Under the Working Time Regulations 1998 (SI 1998/1833), workers have the legal right to 5.6 weeks' paid annual holiday.

The number of days or hours that this 5.6 weeks' statutory holiday entitlement constitutes will vary depending on the number of days or hours that a part-timer works. For example, a worker who ordinarily works only three hours a day on Monday and Tuesday will be entitled not to come to work for those six hours a week for 5.6 weeks, whereas a worker who works from 9am to 5pm four days a week will be entitled not to come to work for those four days for 5.6 weeks.

If a comparable full-time worker's contract allows for longer annual holiday, eg six weeks' holiday, the extra entitlement should be extended to part-time workers on a pro rata basis. The length of service needed to qualify for longer annual holiday must also be the same for part-time and comparable full-time workers.
