I'm aware that the changes have come about entitling employees to 24 days per year including bank holidays. (Rather than 20 days including bank holidays as before). I know that those who were already giving 24 days could absorb the changes without actually giving anyone any more days off.
However....
What I wanted to clarify is that if your contract of employment said "statutory/20 days holiday per annum plus bank holidays, and office closure over Christmas" can it be argued that if the statutory has gone up, then your entitlement goes up too, even if the employer has been quite generous in the first place?
