How does holidays for 0 hour contract employees work?

I was under the impression that as an employee working 3 days a week and I wanted a week of holiday I would just book 3 days of in a week and I would be paid what I’m normally paid for a week. However according to my job I have to book 5 days off to be paid what I normally make in 3 days. Is this a legal format? Because at my old job which is under the same brand I would book 3 days off and get a full weeks pay.
