Someone said :
Sry ok have notice on my job and finished 2 weeks ago had 16 days holidays left. When I asked about them I was told I was only entitled to 3 days and they didn't have pay them
16 days out of 2020?
You would only have accrued 4 to 5 days really for 2020...
If you had some from 2019, they may not be carried over, based on hr policies.
Did you get a severance package ?
What does your contract say ?
Ask them for their hr policies in term of holidays: if they have none you have more of a chance.
Also if you keep them 1h on the phone they are more likely to decide to get rid of you with a payment for 1 week, as you’d cost them more by calling, especially if you suggest you’ll contact the work relations tribunal...
