If you're getting your glad rags on this week for office Christmas party, ensure you don't wake up filled with regret the next day.
Of course, it's accepted you might wish you hadn't had that extra pint or cheeky G&T you necked on the way to the taxi - but make sure it's only the drinks that have you feeling sorry for yourself in the morning.
Here are our top tips (illustrated by Office Christmas Party film trailer as seasonal warning) to make your festive do go without a hitch. And keep you in work when Monday rolls around.
1. Ask for a promotion
Over a plate of canapes and a glass of champagne might not be the best time to raise this subject.
2. Bypass the bar for your round
You might save a few bob, but you'll be known as a cheapskate for the rest of your time at the job.
3. Speak ill of your colleagues
We've all done it - but there's a time and a place. Don't make it at the Christmas party when everyone's trying to get along.
4. Mouth off to your boss
Not the best place to air a grievance. You don't want to wake up unemployed!
5. Send funny pictures to your partner
It's fine that you're out having a laugh with your mates - but it's not so much of a laugh for your partner who's sober, waiting to give you a lift home.
6. Take unflattering photos
While we're on photos, spare a thought for your colleague who might look a little worse for wear. Chuck a filter on the photo first or, even better, ask their permission before that Facebook upload.
7. Take unfair advantage of any complimentary drinks or food
If you're being provided with free food or drinks vouchers, it's fine to have your share. But don't head for the old photocopier with those drinks vouchers, or scran on 100 pigs and blankets!
8. Corner a colleague under the mistletoe
It's just not okay.
9. Go for the sake of it
We hope everyone has a brilliant time - party safely.
