Bank holidays for part-time workers
Most bank holidays fall on a Monday. Without adjustment, someone working Monday–Wednesday gets nearly all of them; a Thursday–Friday colleague gets almost none. The fair (and Acas-recommended) fix: give every part-timer a pro-rata share of the year's bank holidays, whatever days they work.
Fair-share formula (England & Wales, 8 bank holidays)
2026/278 × your days per week ÷ 5
A 3-day worker gets 4.8 days of bank-holiday allowance. Working days that fall on a bank holiday come out of it; the remainder is extra leave.
The legal position, plainly
There is no statutory right to bank holidays off, paid or otherwise — for anyone. What the law does require is that part-time workers aren't treated less favourably than full-timers (Part-Time Workers Regulations 2000). If full-time staff get 20 days plus 8 bank holidays, a fair part-time package is 28 × fraction — the pro-rata approach this calculator shows.
Common questions
I don't work Mondays — do I lose the Monday bank holidays?
More of my working days are bank holidays than my share covers — what happens?
Scotland and Northern Ireland have different bank holidays — does the maths change?
