Agreed with my employer yesterday that it's best I hand my notice in, as I'm in my probation period I've only got to work 1 week. But my mum has said she doesn't understand why I am staying and should just hand the company car back Monday morning and get a taxi home (I do actually need the car over the weekend otherwise she suggested today).
Am I allowed to do this? I'm not worried about a reference as this company only gives 1 line standard references anyway. Also I have no intention of ever working for these people again.
