Spotted over in the comments of the always entertaining DailyWTF:
the boss went off on him, criticizing him for coming in at an unauthorized time, making an unauthorized software change, and for compromising the integrity of the warehouse system. Ah well, so is the life of a contractor
Sounds like its time to find a new contract.
Nope. Anyone who has done contracting saw this coming. The correct reponse is to look contrite, apologize, and add the time spent getting criticized to your bill.
Ahh, the delights of being a contractor
