When I worked in data entry fresh our of college, there was a mass firing. Turns out people were signing in and leaving. Like, to go to the movies, to the store, to just hang out, for their entire shift, and would then log out at the end of the day. Damn near every person under 30 was gone. Some quit before they could get fired. It took all day, and there were plenty of performances. Now, it was data entry, which meant our activity was tracked, from the inactivity to how much we got through in a day. I have no idea how they didn't think anyone would notice.

Worked at sheetmetal manufacturing plant. Had aisles of welding booths. Old dude welder would smoke in the building in his booth letting the smoke get sucked through the table vents. Well sure as ahit one day a little more than just smoke gets sucked up and next thing you know thr whole ventilation system goes up in flames. Never saw the dude again.

Same plant but one of the robot welders, the worker would mount an unrelated electrical box on the robot welder rig. Then hit the foot petal and it would clamp 3 of the 4 sides down with a fuckton of pressure. Months after opening back up after ventilation fire this new chick was running the robot welders and steps on the fucking clamp petal while still holding everything in place. She clamped her whole hand smashing all the bones in her hand I think. Never saw her again either. It was a freak accident not even anything you can point a finger at. I guess she lost balance a little to make her step and didn't have her hands in way so the e-stop light bar that senses if you are in the way wasn't tripped but she slamed her hand onto the box as it was closing trying to catch herself.

They had tons of people I never saw before come in and assess the robots and turret presses and they installed the petals that have covering flaps you need to lift to get your foot in the petal. All in all the place was super safe and the dude that smoked was super fucking belligerent and was going to be fired the next infraction before burning the ventilation system down.

From my current workplace:
Someone was putting mail in a cabinet under their desk instead of the outbox, we're talking hundreds of letters/cheques/invoices and some life-changing documents from a few months.
The mail outbox was on their desk, and easier to reach than the cabinet.

From previous workplaces:

• Breaking down a door and raping someone that had barricaded themselves behind said door.
• Sexual interference.
• not having a licence, and getting a DUI with a work truck that they stole.

And outrageous in a different way:
for only beating last year's sales by 3% instead of by 4%.

Sex in the stock room. Caught by manager.

Different times and companies, but I've seen people fired for

• being in his 30s and sleeping with the 14-15 year-old worker (I forget exactly how old she was). This was working in a movie theater and he was the GM.
• found CSAM on their computer
• many for sexual harassment (a few different jobs in IT)

I think that's it for the NSFW stuff.

I've had 2 coworkers lose their jobs for being diddlers, but nothing other than that really. Only other one 8 have, I didn't get to witness since I was living out of town at the time, but a shithead ex-boss got walked out by some feds and wasn't seen again. Gossip was it was INS, and it would serve him right to get deported.

It wasn’t even the unisex one

An IT company I worked for many years ago went through a massive growing phase. One of the things that lead to this growth was the hiring of much more competent management, particularly in security and the data center.

Security actually started doing their jobs and started routinely doing network scans. They discovered two servers that were not located in the data center, which was a huge no no. The servers were running two porn websites off the company's internet connection. The guy had been doing it for years and apparently was making many times his company salary from them.
