I have recently gone through a couple of job changes and left my last job on the last day of August. In the meantime I have had some time off and only just found myself a new assignment. I actually started today. Yah! I am back consulting for a company that I was with a couple of years ago. But basically I left the August job in interesting situations. They were plenty rude to me and I basically just walked out and didn't go back - they tried to call me a couple of times but I just ignored them. They even sent me out a letter but I just filed it (in the rubbish bin). However today I raided my bank account and realised that my old job have paid me for the entire month of September. Now it isn't a huge amount of money but it is still a full month's wages (it's a few grand) and as I walked out and didn't do any work it shouldn't really be paid to me. I was wondering what other people think of this and whether I should do the "right" thing and offer to return the money or whether I should do a "runner"?
