1. The Gossiper⠀⠀
If they are talking about others to you, trust they are also talking to others about you. What makes you think you get exclusive rights to their loyalty? Sorry to break it to you, but you don’t. If they’re eager to share someone else’s business they’d be all the more eager to share yours. Don’t engage. Nod, smile, play clueless, be vague and write them off as “knowing where to keep them.”

2. The Pessimist⠀
⠀Sure, every job has those few (or many) aspects that you wish were different, but if your co-worker tends to constantly find everything wrong, something’s wrong. No one likes a Negative Nancy. Ask yourself why are they still here if it’s just that bad? Don’t allow yourself to be the company for their misery. It’s contagious and fruitless.
⠀
3. The Suck-up⠀
Understand that these people will often do anything to obtain the approval of the boss, even if it means throwing you under the bus. Yes, you, ideally, want your boss to like you, but at what cost? Align yourself with those who prefer to let their work speak louder than their mouths.⠀
⠀
4. The Idle⠀
Why does this person never have anything to do? In a workplace, that’s a little weird. The person who tends to spend most of the day floating around the office or hanging out at your desk is either avoiding or displacing their work. These employees typically are distractions and bad influences. Also, if you notice that they’re rarely working, others, including your boss, likely notices too. Never forget that association brings on assimilation. Keep your distance if only to preserve your reputation.⠀
⠀
5. The Thief⠀
There is always that one co-worker who does little but claims lots. Avoid allowing this type of worker into your space. Their antics are frustrating as they’re constantly on the prowl for your ideas, your resources, and your energy. This simply can’t fly. It’s all fun and games until they’re taking credit and being promoted for all the hard work you’ve done. Feel free to keep your brilliance to yourself.⠀

6. The Leech
They're setting themselves up to be your understudy and will be the first to turn on you. They will act innocent and naive but they truly know what they're doing. They know what cards to play in order to look like the sweet, innocent docile damsel in distress once they do turn so that if you do try to call them out you look like a hater and handicap yourself even more. Long story short, make no friends inside of the work place. Stay amicable acquaintances and hang out with your friends after work at happy hours and brunches.

7. The Worrier.
No confidence in performance. Afraid to try things differently. Believing the world will end with the tiniest of mistakes.

8. The conversationalist.
Just talks non-stop & you couldn't care less about their personal life, weekend plans or their small talk. One word answers won't shut them up either. They can't take a hint.
