How does holiday entitlement actually work?
Almost everyone in work is entitled to a statutory minimum of 5.6 weeks' paid holiday a year — and the confusion comes from the fact that this is expressed in weeks, not days, which is what makes part-time and irregular working straightforward once you see it.
The basic rule. 5.6 weeks of your working week. Someone working five days a week gets 28 days; someone working three days a week gets 16.8 days. The entitlement scales automatically, which is why the weeks-based framing exists.
Bank holidays are not a separate entitlement. There is no statutory right to bank holidays off or to extra pay for working them. An employer may include the eight bank holidays within the 5.6 weeks — which is very common — leaving 20 days of chosen leave for a full-timer. Whether they are included is a matter for the contract.
The maximum an employer must give under the statutory minimum is 28 days; entitlement above that is contractual.
Irregular hours and part-year workers have their own method, accruing holiday based on hours actually worked in each pay period, with rolled-up holiday pay permitted for these workers — a change that resolved a long-standing area of confusion.
What holiday pay must include. Not simply basic salary: where someone regularly receives overtime, commission or certain allowances, these must be reflected in at least part of their holiday pay. This was established through a series of cases and is frequently got wrong.
The points that cause the most disputes:
Carry-over. Generally leave must be taken in the year it accrues, with limited exceptions — including where someone could not take it through sickness or family leave.
Employer-directed leave. An employer can require you to take holiday on specified days, with notice of twice the length of the leave.
Refusing leave is permitted with proper notice.
Sickness during holiday can generally be reclaimed as sick leave.
On leaving, untaken statutory holiday must be paid; contractual extra may or may not be.
Accrual during maternity and other family leave continues.
