I have been in a job for 5 months and in my contract it said i must give 4 weeks notice which i have done.  I thought my employer would need my help training a new employee however this is not the case and i have been basically stripped of all duties and am doing not much of anything.  My boss then said to me one week into my notice period that if I agree I could finish after 3 weeks which i agreed to - now I am wondering if I only had to give 2 weeks notice as per the NES and if so I could leave in 2 days. Can anyone help me here?  I dont think i am under an award - i basically do an admin role but my contract says accountant/bookkeeper.  Can i leave after 2 weeks or am i now obligated to leave after the 3 agreed on?  My 4 weeks notice is in writing and the 3 weeks agreement between us is verbal only.  What should i be paid for - the 4 weeks or the 3?  Sorry a bit complicated!
