I handed in my notice for my job last week. However this week I have been told by my new employees that I won't be able to have the hours that I want which they initially said would be ok. This will mean a lot of juggling around etc. I don't know what to do now and not sure if I should take the job or if it's too late to retract my notice. And will my employer be pissed of with me for wanting to leave and then asking for my job back!
