Thanks China Doll, don't worry about being harsh - but actually I think maybe you're right, it be better to honest now, instead of leaving it later. It's going to be difficult either way really, I'm on 6 months probation, so they can kick me out whenever they feel like it for whatever reason anyway, and there's nothing I can do about it. That's why I'm reluctant to be "honest"
I think I'll speak to them about reduced hours first, and see what happens, then maybe judge things from there on... depending what happens
thanks for answering though :)
