Survey reveals drinking too much booze is the worst holiday party mistake

INDIANA – Holiday parties are a festive highlight of the work calendar – but they can also be a professional minefield. It’s the one night when questionable dance moves, overshared gossip, and a little too much eggnog can collide in full view of your colleagues – and, worse, your boss.

While these celebrations are meant to bring teams together, they can sometimes lead to career-damaging moments that overshadow years of hard work. The career experts at resume.io surveyed 3,000 managers in Indiana to uncover the most memorable mistakes they’ve witnessed in office parties across the Hoosier State.

The top 15 worst party pitfalls among Americans are:

1. Drinking Too Much Booze
Overindulging in alcohol is a classic party misstep, say managers. Slurred speeches, embarrassing confessions, or even a stumble into the Christmas tree can leave lasting impressions – and not good.

2. Not Showing Up
Skipping the party altogether can come off as aloof or disengaged. Managers often notice who makes the effort; an absence could send the wrong message about your team spirit.

3. Flirting with Co-Workers
What might feel like harmless banter after a few drinks could easily cross professional boundaries. Awkward Monday morning meetings or whispers around the office aren’t worth the fleeting thrill.

4. Inappropriate Dancing
Managers cited inappropriate dancing as the fourth biggest party pitfall. The dance floor is no place to unleash moves better suited to a nightclub. “Keep it light and fun—no one wants to become the star of the office party’s viral video,” she continues.

5. Bringing an Uninvited Plus-One
Arriving with a surprise guest can create logistical headaches for organizers and awkwardness for the group. Always respect the invite’s parameters.

6. Oversharing Personal Gossip
Revealing too much about your private life—or someone else’s—can quickly backfire. “Remember, the office party is not a confessional booth, and trust is hard to rebuild,” says Amanda Augustine, career expert at resume.io.

7. Bringing Leftovers Home
Yes, the food is free, but loading up Tupperware for the week ahead sends a message that’s more “desperate” than “resourceful.” Enjoy the buffet, but leave some for everyone else.

8. Unfiltered Opinions
A few glasses of wine can loosen tongues, but airing grievances about the company, coworkers, or even the boss is a fast track to career trouble. “Stick to neutral or positive topics,” advises Augustine.

9. Gift-Giving Fails
Whether it’s a thoughtless Secret Santa gift or something wildly inappropriate, gift blunders are hard to forget. Aim for something simple and workplace-appropriate.

10. Disrupting the Speech
Heckling the boss during their toast or making loud side comments can turn you into the office Grinch. Augustine suggests remaining “respectful and attentive during every company speech or presentation—no matter where they are held.”

11. Social Media Missteps
The 11th biggest festive fumble is posting unflattering photos or videos from the event—it can damage reputations—not just yours but also your colleagues. “Always think before you tag,” warns Augustine.

12. Aggressive Networking
While it’s great to connect, monopolizing a senior manager’s time with career ambitions can come off as pushy. Save those conversations for a formal meeting, not the dance floor.

13. Cliquey Behavior
Try mingling with different colleagues throughout the night rather than staying with your usual work group. It’s a great chance to get to know people from other teams and helps everyone feel included in the celebration.

14. Wardrobe Malfunctions
A too-tight outfit, overly casual attire, or a malfunctioning zipper can quickly overshadow your professionalism. “Aim for festive but appropriate attire that won’t cause distractions,” says Augustine.

15. Winning Ugly
Finally, and in 15th place, whether it’s a raffle, trivia contest, party game, or gloating about a victory can dampen the festive mood. Celebrate gracefully or lose with humor.

The top three in Indiana were:

  • Drinking too much
  • Flirting with coworkers
  • Not showing up

The format and theme of holiday parties play a significant role in how events unfold. Unsurprisingly, holiday parties with open bars are the most likely to encourage mischief, with 72% of managers citing this setup as the biggest culprit. Comparatively, ugly sweater contests (9%), karaoke nights (9%), and game nights (10%) lead to significantly less chaos.

Awkward Conversations Overheard
Holiday parties may bring people together, but they can also create conversational minefields. Managers shared the most uncomfortable topics overheard at office parties:

  • Inappropriate personal stories: 36%
  • Politics or religion: 23%
  • Office gossip: 21%
  • Complaints about the company: 20%

Redeeming Yourself After a Blunder
If you find yourself guilty of a party faux pas, the managers surveyed identified the most effective ways to recover:

  • Apologize to the affected parties: 59%
  • Make light of it with humor: 20%
  • Pretend it didn’t happen: 13%
  • Volunteer to plan the next party: 8%

Memorable Moments That Last

  • Group games or competitions: 35%
  • A lively dance floor: 23%
  • Karaoke performances: 26%
  • Speeches or awards: 17%
