Get too drunk: Look, no one wants to wake up the morning after the work Christmas party not remembering a damn thing because they drank too much. Have fun, let your hair down, but go easy on the beveragino2, ok?Forget to drink water: Along with taking it easy on the alcohol, don’t forget to drink plenty of water. It’s key to staying hydrated (obviously) but pro tip: it’s the best way to wake up without a hangover too.Leave early: Not everyone is a social creature/enjoys Christmas work parties, but try your best not to smoke bomb too quickly. It’s not great for team morale! Stay for a couple of hours if you can, and don’t forget to say goodbye when you leave.Critique the music: No one likes the person who complains all night about the music, so don’t be that person. If everyone’s taking turns choosing the playlist, wait your turn! Or, if the person who organised the party is in charge of the tunes, let them choose whatever they want (and if you want a say in the music next year, volunteer to organise the party).
