Most people spend more time with their coworkers than with friends or family, so it’s important to know when something’s a little… off. Whether it’s subtle behavior or full-on drama, some red flags are too big to ignore.
From backhanded compliments to mysterious disappearances, these warning signs can spell trouble in any workplace. Here are 15 coworker red flags that should definitely raise your eyebrows—maybe even both.
15. They Always “Joke” About Quitting

Every day is a dramatic countdown to their last day. It’s funny until it starts tanking morale.
14. They Love Gossip — Especially About People in the Room

They’ll throw anyone under the bus with a smile. If they’re talking about others to you, they’re definitely talking about you to others.
13. They Take Credit for Group Work

They somehow end up as the hero of every team project. Funny how they’re always at the front of the parade without doing the heavy lifting.
12. They Never Take Responsibility

Everything is someone else’s fault—always. They’re allergic to accountability and quick to deflect.
11. They Constantly “Forget” Meetings or Deadlines

Once in a while is human. Every week? That’s a red flag waving in high definition.
10. They Micromanage Everyone

They don’t trust anyone but themselves. If you’ve got someone hovering over your desk for no reason, it’s time to set boundaries.
9. They Brag About Doing the Bare Minimum

They’ll proudly tell you how they coasted through the week. Not exactly the energy you want on a team trying to get things done.
8. They’re Always the Victim

No matter what happens, they’re the ones being wronged. Drama follows them like a cloud, and they’re never the problem.
7. They Undermine People in Meetings

They’ll throw out a passive-aggressive dig and pretend it was helpful. It’s not feedback—it’s sabotage in disguise.
6. They Love Playing Office Politics

They know exactly who to charm and when. You never quite trust their smile—or their motives.
5. They Act Completely Different Around Management

One personality for coworkers, another for the boss. It’s like watching a Jekyll-and-Hyde routine.
4. They Refuse to Help Anyone

Need a quick favor? Don’t ask them—they’re “too busy” unless it benefits them.
3. They Treat Everything Like a Competition

They can’t just do a good job—they need to beat everyone at it. Even casual conversations feel like a race.

2. They Overshare Personal Drama
