1. This Co-Worker’s Poop Incident

“I worked at a bakery. One day I went to get a mop and instead found a huge pile of human poop. On. The. Floor. I got a manager, and we began to investigate. We came to find out that a woman who worked there had to go to the bathroom, couldn’t hold it, shit on the floor, and told no one. She didn’t understand why everyone was so upset and insisted she just hadn’t had time to clean it up yet. She definitely got fired.”

2. The Actions of A Co-Worker Resulted In This Person Being Told By The Company To Work From Home

“I had a co-worker lose his marbles, started texting me all sorts of weird stuff, and wanted to do some sort of murder-suicide pact after he walked out in the middle of the day without saying a word. I was the only person on my team he did this to. Cops and corporate security teams got involved. My team was told to leave the building and work from home for a while. I still work from home. I guess it worked out pretty well for me in the long run.”

3. The Co-Worker Who Picked Her Nose While Cooking

“Last year I worked at this diner, and one time my co-worker picked her nose and threw the booger into the spaghetti sauce she was making. She grabbed a spoon, and instead of getting the booger out, she asked me if I wanted to taste the sauce.”

4. This Co-Worker’s Coughing Fits

“Currently working with a person who has had a sinus infection since November 2016. That’s right: wet, chunky coughs, 9 hours a day, 5 days a week, for going on 10 months. No, she does not leave the team area for coughing attacks, she just retches up whatever it is and gulps it back down. 10 months of that in a quiet office.”

5. What This Person’s Co-Worker Does After Picking Her Scabs

“I worked with someone who picked her scabs off her face and ATE them. We worked in a daycare center, which made it even more gross because she would do it in front of the kids.”

-Shadebutnoshade told BuzzFeed

6. The Co-Workers Who Took The Advantage Of The Bed

“I worked at an escape room, and one of the rooms had a bed in it. Two of my co-workers were dating, and they decided to make use of it, having sex several times on the bed. And the worst part is, speakers are always on in the control room, so we heard a lot of things.”

7. The Co-Worker Who Staged Incidents So She Could Be Seen As The ‘Hero’

“I have several bad ones but the one [co-worker horror story] that drives me the most crazy is a lady who creates problems just so she can solve them. Ugh. She takes a simple job, finds the one tiny issue, blows that up and freaks everyone out, and then “solves” it so she can be the hero. Just take the 1 minute to fix the issue in the first place. It would save the literal hours she spends working everyone up so she can be their savior.

8. The Co-Worker Who Probably Had HR On Speed Dial

“I had a male co-worker who was openly gay and would call HR regarding every conversation he had with me that he didn’t like. Our conversations would include why he didn’t do his job or clean a particular area like he should have. His HR complaints would be along the lines of “DanHalenSRI thinks that because I’m gay I should be the one cleaning like a woman.”

I was interviewed by HR every week for months and eventually had to contact management anytime I wanted to relay information to him. Instead of punishing him for making false accusations, they moved him to another department so that he didn’t have to go through the mental stress of having real-world conversations.

Any time I would apply for a promotion I would get a canned response of “you’ve had too many investigations against you for us to consider you for this promotion.”

Worst experience with a co-worker ever.

9. The Old-Fashioned Co-Worker

“I have a co-worker who’s very old-fashioned and strongly believes that males and females cannot be friends. Well, it just so happens that my manager and I, a male and a female, happen to get along quite well because of our similar ages and interests. She reported me to the other managers for it and accused me of sleeping with him.”

–Redditor Rosatenea

10. How This Person’s Former Co-Worker Got The Nickname “The Chanel Bandit”

“This is about 15 years ago but the office I worked in instituted a scent-free policy. One woman, who was already insufferable, was so offended by it that she snuck in her perfume collection.

She’d walk down the halls and spray perfume into empty offices or cubicles when no one was looking or before everyone arrived in the morning.

This went on for well over a month or two and we had no idea who was responsible. My coworkers and I started referring to this mysterious person as the Chanel Bandit.

She was finally caught on camera in the act. She’d left for three weeks vacation and was unaware that we had installed cameras after a break-in. Some of us already suspected her, as the Chanel Bandit mysteriously stopped spraying while she was away.

She quit right after she was caught. None of us were sad to see that cedar scented psycho leave.”

11. The Scamming Co-Worker:

“My worst co-worker was one I worked with when I was a cashier at Walmart. She approached me and asked me to cash out her paycheck. I was still new at the job and never got training on how to do that function. She was sympathetic, so she walked me through how to do it. Transaction over and was done, I go on about my day. I get called back a couple of days later by my managers and they circled me in an office and accused me of stealing. After tears, videotapes, and telling them what happened they told me that apparently, this coworker of mine had stolen not only from me but several other people that day as well. They just wanted to confirm I wasn’t in on the deal.”

–Redditor JelloJock

12. The Co-Worker Who Eats Too Loud

“This coworker sits next to me at the office. He eats fast food at least one or two times a day, every single day.

He refuses to eat his food anywhere but his desk and will shovel ten fries at a time into his mouth and chomp on them incessantly. He makes as much noise as possible with the wrappers and slurps his extra large drink like someone is about to steal it from him.

Worst of all, when the drink is clearly gone, he will suck harder and make the loud whistling and gargling sound of a drink that is no more.

I’ve dealt with it for so long I can’t stand the sight or smell of [fast food] anymore. My friends and I keep a daily tally every time he shows up with fast food — last month, he racked up about 30 tallies.

And that’s only what we saw for sure.”

-Cory told Business Insider

13. What This Person’s Co-Worker Does After Clipping Her Nails (Finger and Toe)

“One of my coworkers would clip their fingernails and toenails and then proceed to throw them at people. When she got the nail clippers out, that’s when everyone knew to get away.”

-Izzydog777 told Buzzfeed

14. The Co-Worker Who Can Be Considered A Stalker Due To The Contents Of Her Spreadsheet

“My previous manager kept a spreadsheet to track every single minute of my day. If my productivity was lower for a particular day, she would pull me into a meeting and present all the past spreadsheets and ask why I was not being productive during XYZ minutes. She tracked the minute I clocked into work, how long I spent in the bathroom, how long I stepped away to get a cup of coffee in the break room, and how long I talked to customers.”

-Victoriaa43d5503fc told BuzzFeed

15. The Co-Worker With Weird Eating Habits

“I was working a one-night gig helping collect and organize ballots and equipment at the county office on election night. One of the other workers was eating yellow mustard packets you get from fast-food restaurants. She would just take one, rip it open, and squeeze it into her mouth. She probably went through 2 dozen over the 6-hours that I was there.

I’m a big fan of yellow mustard, but it really grossed me out. I’m not sure if I was more freaked out by my county’s voting record or her snacking habits.”
