I don’t know to be honest. They have a min of £350 a day work Mon-Fri. Not sure how that works in terms of your question. I think a zero hours contract means I’m not obliged to offer them work.
But that’s not the case as they’re getting a set amount of work each day, for a basic rate of pay that equates to well above full time minimum wage.
What the specific legal definitions of it are I do not know though. I’m not an expert on contact law. I’m sure there are plenty of jobs which are defined by responsibilities rather than set work hours though. And they aren’t all zero hour contracts
Who knows though. Maybe I’m wrong eh 🤔
