Hello Alan my name is ***** ***** I am happy to help you today. What scheme do they say the holidays were tied up with?
Ok thanks does the letter from January this year acknowledge you are entitled to this holiday?
It is unusual for a company to agree to pay holiday rolled over for such a lengthy period. However given that they have told you in writing you will be paid it is my view that it is payable so you would be able to bring a breach of contract claim against the employer if they do not.
You should tell ACAS therefore that you want to start early conciliation and if they do not pay then you can bring a breach fo contract claim in the Employment Tribunal.
If you have any further questions please do ask. if I have answered your question I would be grateful if you would be so kind as to rate my answer. Thank you and all the best.
