Letter of appointment
I know of a couple of guys that have been approached or promised a job on contract with them, only to find that nothing has/is coming about it.
Even heard of one guy actually starting there and then battling to get an appointment letter from them....things did not work out to well as he never got an appointment letter.......he got a bye-bye letter though.
They used to be a great company to work for, (and probably still are), but make sure that you get everything on paper before resigning from your present position.
