Annual leave part time

54 replies

Mondayneverends · 21/04/2026 17:58

I work 20 hours per week 4 hours each day Monday-Friday. Full time annual leave is 25 days. I’ve been told I will get 13.5 days (full time week is 37.5). In previous jobs my annual leave was in hours, so I would get 100 hours. Is it better to book time off in hours or days? I’m a bit confused by it.

A lot depends on what happens when you take time off.

If you take one day off and they deduct 0.5 of a day from your holiday allowance, they are actually being generous and giving you a little more holiday than your entitlement. You will get 108 hours whereas you are only entitled to 100 hours. However, if they take a full day off every time you take a day off, they are acting unlawfully by short changing you on holidays.

If I book a day off, it takes off a full day from my allowance. I don’t think this is correct after reading all the comments.

Is it right that I get 25 days to book? Obviously I would only get paid for 4 hours not 7.5 hours. I guess I am in every day so it makes sense I should have 25 days off. Also if I had the entitlement in 100 hours and booked off 4 hours at a time, it works out to be 25 days available to book.

Yes, you should have the exact same entitlement as full timers but pro rata.

pro rata in your case means each day is 4 hours long rather than however many hours a full timer works.

dementedpixie · 21/04/2026 21:40

A full timer working 37.5 hours gets 33 days in total so their holiday in hours would be 247.5 hours.

As you work 20 hours over 5 days you are also entitled to 33 days holiday which would be 132 hours.

20/37.5 = 0.53 of full time. 132/247.5 = 0.53 of full time (just showing that the figures are correct)

They are totally wrong in their calculations and are doing you out of lots of holidays

dementedpixie · 21/04/2026 21:47

Another way to look at it is that full time staff are entitled to 6.6 weeks worth of holidays (33÷5).

You would also be entitled to 6.6 weeks worth of holidays which would be 6.6 x 20 (hours) =132 hours = 33 of your 4 hour days.

What they are doing is wrong. As you work a 5 day week, you should get 25 days the same as everybody else. The fact you work fewer hours does not justify reducing the amount of holiday leave you get.

I agree that the best way would be to do it in hours, so you would get 100 hours.

Thank you. Should I ask them to change my entitlement to hours or change my days to 25? They use BrightHR. Bit worried about how I’m going to explain this to them.

She has got 25 days - she has 100 hours which is 25 x 4 hours! All of this can be cleared up by confirming that you book your A/L in Hours.

dementedpixie · 21/04/2026 21:55

Dont forget the 8 bank holidays as you are entitled to them too if full timers get them. Not sure on the system they use. Do they calculate other staff members in hours or is it all in days?

She has already confirmed that she is not able to book her holiday in hours.

She said she had 100 hours in her previous job, not this current job

cucumber4745 · 21/04/2026 22:03

13.5 days is 100 hours. Speak to HR on what is best way to book. You are not entitled to 25 days as someone suggested because you work 5 days. Calculations are based on number of hours relative to the full time week over the pay period. It comes to something like 12%

I could ask if they can set my entitlement in hours instead of days. There is the option to do this on the system.

13.5 of OPs days (4 hours) = 54 hours as OP has said 1 day gets deducted for every day she takes.
She is not able to book in hours, only days, so you are incorrect

If its easier then ask to do it in hours then
6.6 weeks at 20 hours = 132 hours holiday (unless they do the bank holidays separately)

Thanks, I will make a note to check all of this. I’m the only part time employee. Everyone books their time off in days.

They are mixing up days and hours, so yes your leave shoukd be worked out in hours. 13.5 x 7.5 =101.25. It’s 53% of 25 full days, and 20hrs is 53% of 37.5hrs. So in theory they are correct. But you only take 4hrs off for each day off you take. So in actual days away from the office, you also get 25. It’s just yours are shorter.

Tell them it needs to be given to you in hours, not days.

This is not how leave is calculated. It is 12.07% of the hours worked per pay period. So if OP works 80h a month they will get 80 x 12.07% =9.656 hours a month. Over a leave year that is approx 116 hours which comes to about 15.7 days assuming a full time work day of 7.4h. So the 13.5 days OP is getting are likely full time days and that needs to be clarified with HR. Standard annual leave is not 25 days

I work 4 hours a day not 7.5, so I am not sure this is correct based on what everyone else has said.

topcat2014 · 21/04/2026 22:15

You still need to book holiday in days, as you work the same hours every day. Get directors involved if the admin people are failing with this very basic concept. There is no ambiguity in your case.

topcat2014 · 21/04/2026 22:16

You are absolutely entitled to 25 of your 4 hour days. There is no argument on this

dementedpixie · 21/04/2026 22:16

@cucumber4745 the minimum annual leave in the UK for full time staff is 28 days which can include bank holidays. I dont know where youre getting your calculations from!

Yes this is wrong. Either you

  1. get the same number of DAYS as a full timer because you work the same number of DAYS as a full timer
  2. or they work out all proportionally so you get the same proportion of hours leave as a full timer. Otherwise you get less days off than a full timer which doesn't work.

It doesn’t matter what standard annual leave is. What matters is that the full time equivalent in her team is 25 days (plus BHs). The OP gets pro -rata of this. My numbers are correct.

I’m curious as to where you get 12% from. 12% of what?

Comefromaway · 21/04/2026 23:09

Cucumber you are totally wrong.

the 12.07% calculation is used for employees who work differing numbers,of hours per day/week, often casual employees.

IN OPs workplace full time staff get 25 days plus bank holidays (33 days total or 6.6 weeks. Legally as a part timer she is entitled to the same number of weeks holiday as a full timer. If she books 1 weeks holiday she is entitled to be paid for the same number of hours as she would get for a normal working week.
