Sorry, I meant to respond to post #8. The wages per se weren't my main concern. When people are offered bribes at other people's expense I think it is only decent that the people doing the paying be consulted first. I wasn't. There is also a second principle, should people accept a wage offer because they are being bribed or should they accept a wage offer because it is commensurate with the work they are doing?
Signing bonuses are very common.
