Workplaces all over the UK are preparing for Christmas and all the traditions and customs that come with it. But will this Christmas be a cause of happiness and celebration, or of disappointment and embarrassment?

At this time of year, colleges show their appreciation of each other by doing a “Secret Santa”. Secret Santa involves people who work together buying gifts for each other without saying who they are from.

Co-workers all write their names on pieces of paper, then organize a lottery in which each worker picks a colleague’s name at random. He then has to buy a present for that colleague, usually on a small budget of five or ten pounds.

Since the givers are unknown, the quality of presents can vary greatly. In an Internet survey of Secret Santa presents, the gifts that people received range from tickets to the opera to an air freshener for a car.

Another common workplace tradition is the office Christmas party, at which workmates put on their best clothes and enjoy lots of free wine.

Most parties go without a hitch, but sometimes the alcohol cause party-goers to behave in a way that they later regret.

The BBC invited people to share their most embarrassing Christmas office party stories, and received hundreds of funny ones. For example, a man split his trousers while dancing; a drunken lady spent the whole night with the edge of her dress folded into her pants, and later looked at photos that proved it at work.

But the funniest story must be that of Stuart Vanies, who got so drunk that he put his boss’s head into the toilet. Unsurprisingly, he was fired the very next day.
