I always thought its the companies decision on what amount of holiday you get/they entitile you to

I know people who only get two weeks paid holiday a year, I have worked for my employer for 15 years and i get 26 days or 5 weeks and 1 day a year, one i get to 20 years if i get that far my entitilement will go up to 6 weeks a year,
personally i think we should all get 40 weeks a year
