Relationships with colleagues can be tricky. In a way, it’s similar to school: a bunch of people thrown in together with little to no things in common, spending most of the day in each other’s company. It’s certainly not an obligation to like your colleagues, and many people don’t. In fact, a 2024 Forbes report found that 85% of Americans deal with annoying coworkers.
Few things are probably worse than having an idiot for a colleague. In the best-case scenario, they’re going to be a constant nuisance. In the worst case, they might endanger you, themselves, and everyone around them.
There are all kinds of idiots in workplaces everywhere, as this recent online thread makes clear. “What is the dumbest thing you’ve ever seen a coworker do?” one netizen asked, and after reading the replies, you might think that some of these adults should go back to school and learn the basics.

Ex coworker now. Told all of the guys at work that he was quitting. Not by turning in his two weeks but by just packing up and clocking out. He also blabbed that he'd take company tools with him. Word got back to our supervisor and said supervisor made him hand over the company tools before firing him. He has a stay at home wife and at least one kid to take care of. I still don't know what he was thinking.

Start a fire in a chemistry lab in the morning because he didn't account for the reaction evolving gas that spontaneously ignites in air leading to a small explosion. That was bad enough. Then he set the same experiment up in the afternoon with no changes, and went home. When we defused the problem, we estimated we were within an hour of another explosion.

Worked in the Deep South with a German fella. Our workforce was about 75% black. He wore a giant confederate flag belt buckle to work one day. He then tried to justify it by saying it was the battle flag for the army of Virginia.

Received feedback from a code review, then tried to run a snippet of suggested code shared in the code review notes. Emailed the code reviewer to say “hey this code doesn’t run.”
He copied and pasted the code from a word document and tried to run it with the bullet points still in it.

Back when I worked retail, there was one girl who constantly screwed up change.
I'm not talking missing a dollar, either. There was once instance where she gave the customer back both the wrong dollar and cents amount, and it was something like $14.63 in actual change, and she gave back $11.24 or something like that. It was so ridiculously wrong, and it wasn't the first time either.

Maybe more naive than dumb, a coworker was told to make copies and she disappeared all day. I went to check on her and she was feeding each sheet of paper individually.

Carpenter. me and boss were ripping a smaller piece on the table saw. was a 1 man thing, he was just butting in. I feed the piece in and he pulls it out. I turn the saw off, I notice him glancing at the pieces and I basically saw it coming; he dropped the scrap piece on the table saw from like 2 feet up, it bounced and caught the blade and it flung the piece at me at Mach speed. it smacked me across my chest like, wide-ways so it didn't hurt but I just looked at him like he's a stupid idiot and he looked at me like oh man I'm so sorry. got very lucky, that I didn't have to beat up my boss that day lol.

I'm a custodian at my place of work. Someone who is not a custodian used my vacuum cleaner to clean up a spilled iced coffee. It's not a "shop vac", it's not for wet messes. He left the vacuum cleaner all sticky and then told me "it shouldn't be sticky" when I went to go tell my boss that I couldn't vacuum that day because of a mysterious sticky goo all over my vacuum.
That happened 2 weeks ago and the hose is slowly becoming clogged with dust becuase the inside of it is still sticky. I am waiting to talk to the owner about what happened. In the meantime I'm just gonna use it until it breaks. The suction is worse after that guy ruined it and the job takes twice as long now.
I just don't understand why someone would use a vacuum with a bag in it to clean up a sticky liquid mess when there are towels available.

A district manager for a retail store chain emailed the entire company that there were too many women managers. He thought he was emailing just one person. Yes he still has his job.

It was more like a series of things that made us all wonder why he'd even wanted the job.
There were two of us who started on the same day, and we had a ninety-day probationary period before they'd decide if they wanted to keep us there. On day one, the other guy complained that my husband was working too fast. I told him he'd get no sympathy from me.
On day two, he decided to hound the supervisor about the tasks for the day. This was a job with no set daily tasks - we worked on what was given to us - and the supervisor hadn't had his coffee yet. The supervisor's response was basically, "I'm already tired of this kid, he can go to the other supervisor."
Sometime around day five or six, the employee started complaining about his shoes getting dirty. In a warehouse.
He quit on day eighty-nine. I mean, I understand if you think you're not going to make it past the ninety day period, but at least come in for a few more hours of pay?

On an All Hands meeting, a director meant to inspire us about perseverance through tough times but what he actually did was ramble for 30 minutes about how once he tried to assemble a patio furniture set in his living room so he could watch golf while he assembled but it took forever because he made constant mistakes, then when it was complete, it was too big to fit through the patio doors so he couldn't get it outside. It was stuck in his living room.
This man was a hair below the C-suite. Truly inspiring. .

We had a new sales guy start, and on his first week...
He refilled the 5 gallon water cooler. But he tore the lid off before turning it upside down to put it on the stand. Yep, 5 gallons of water on the floor.
The whole sales team was going to the Braves game, and at some point, presumably with alcohol on board, he fell down the stairs. Scrape the hell out of his legs and face.
Then when they come back to the office for everyone to drive home, he left his brand new laptop in his car. And it got stolen.
He actually stayed employed. He was very nice.

I used to work at a data center with poor cooling. To help out, we had these giant industrial fans blowing down some of the rows.
Procedure was that if you needed to get into that row to access something (and the other side was blocked by the wall), you turn off the fan, wait for it to stop spinning, then move it and do your thing before turning it back on.
Coworker decides to be lazy and move the fan without first shutting it down. His finger slipped through the fan grate and it got cut off.

Someone decided to reheat leftover fish in the breakroom microwave for 10 minutes. The smell was so biological and aggressive that we had to evacuate the office and hire professional cleaners.

We were hosting a street festival and had the road closed for the day. Someone had too much to drink and got sick on the blacktop and one of my coworkers tried to mop the street.
Like…just straight spreading vomit and mop water. Eventually she gave up and got a broom and dustpan. Guess how that went.
