The Building office christmas party is tomorrow. We'll let you know on Monday if we took our own advice

The most memorable social event of the working calendar. Who went, wore what, snogged whom. Bad behaviour at the Christmas party has ruined many a promising career so be very, very careful. Never get totally lashed, sit on your boss’s lap or indeed lap dance. If you have an amorous eye on a colleague, don’t hound them like a stalker. Do use the opportunity to be rude to anyone who works for human resources: say it with a smile and they won’t realise – but it’ll give you great satisfaction.
