Have said will work at my old job over half term (left work when had dc 5 years ago - have gone in as a freelance off and on) to help out my boss, who I thought was a friend, and did need a bit of money.
Then find out that after I had tried to get my pay up a bit, to what I thought was a normal level, and he refused...a colleage also coming in to help over half term is getting double! Feel like telling him to get f*cked...which means no new coat for me, but just feel so humiliated.
