Part of my last job was coordinating office moves on our campus. My big boss's wife had been working in HR. Her office neighbor decides she wants her office. No problem. She loves her desk and wants to take it in there, so we’ll have to switch the desks around. No problem, me and my guys can knock it out in a few hours.

I still have my hat on and move the chair and get on my knees with my flashlight and I’m staring into a giant pile of dripping glue, covering every surface I can see under the desk, the bottom, the sides, the drawer return, everything. I’m like why in the f**k would anyone use this much glue to put this desk together, none of my guys would ever be this sloppy.

OH MY GOD IT'S BOOGERS! No joke or exaggeration, boogers where covering every surface. Years of accumulation. -browncoat47

On many cattle farms when a calf dies at birth it's important to get a replacement calf (usually from a dairy herd or from a cow with twins) so that the cow is regularly sucked (avoiding mastitis) and you don't carry a empty cow for a year.

My father... took no such chance, a vet and very good surgeon he would skin the dead calf very quickly and stitch it into a little jacket that we would put the new calfs legs through the little sleeves where dead calf's legs had been and with a couple adjustable strands of twine make a perfectly fitting leather jacket for the calf. Then this confused baby animal wearing the still fresh and bloody skin of the dead calf would be brought to the calf-less cow to suckle at the teat. -say-something-nice

I found 3 dead bodies at the job I worked after college. The first two were shocking but not surprising. They were old and as they were in a halfway home situation they had had rough lives. One died of heart failure and the other of respiratory arrest.

Both messed me up for a couple days. The 3rd one still gives me nightmares. She had been dead in an un-air-conditioned room for three days. The post mortem contractions curled her into a ball (with her face pointed at the door so when I opened it she was staring at me with no eyes in her sockets.) -Spodson

There was a guy fired for spitting in the coffee everyday. Every time he made a pot he would spit into the grinds. Why, you ask? Mind control. He thought if enough people in the office drank coffee with his spit in it, he would be able to control their thoughts, read their minds, etc... -heavymtlbbq

Big ticket item was there was a 5 foot hole in the ceiling of the workshop. Every time it rained we would be flooded with at least 2-3 inches of water. I’d be sitting in my office doing typography designs and my chair wheels would be submerged in the water. I had to put my feet on milk crates in order to stay dry. -BanditCT

Worked airport security (think the TSA, but not American so only like 50% as awful). Was searching someones bag, as it was believed they had a brick of something in the bag we needed to make sure wasn't... kaboom-y. I opened the bag and looked inside.

The smell, indescribable. As soon as I opened it I got hit with the most foul stench I could imagine, like sewer gas but worse, somehow. I look inside and the bag is full of dirty adult diapers. -Ki11Switch654

Different kind of gross, but it's pretty obvious who is in the mascot suit if you're paying attention. Employee walks into closet. Giant Mouse comes out. I'd be doing children's parties and start hearing dads say "Mmm. [Mascot Name] is so hot." "Ooh I want to f**k [Mascot Name]." It was awful. -kw5112

Used to work as a dog bather at a grooming facility. Anal glands. Oh, the stench. And if you're not careful, you'll get hit in the face and smell it the rest of the day. Happened to me a couple of times. -wolf_kisses

My former boss was just a disgusting person in general. He would chew gum a lot and often he would take it out of his mouth and put it down on his desk to 'Save for later'. We had a laptop in the conference room that was hooked up to the TV, and he rested his wet chewed gum ON THE LAPTOP. -Thoraxe123

If I ever see that my old chef is working at a restaurant I'm eating at, I will walk out. I once told him that a big pot of stew that had been left in the fridge had some mold floating on the top. He got a spoon, started stirring it up saying, 'I can't see any mold.' -j-c-s-roberts

Worked a job for a few years cleaning out abandoned houses and apartments to prep them for renovation. So the crew I'm with arrived at a two story home, with only the knowledge that it had a mouse infestation. Upon entering, mice went scattering under (and in some) furniture. There was mouse feces everywhere and on everything. There was old furniture, broken appliances, and left over food in many places.

So much mouse poop we couldn't see the floor underneath at that point. -Version_Red

Pulling the pilot's body out of a plane wreck that had been missing for six months. Let's just say it wasn't great. -Important_Outcome_67

A place I used to work at had a bathroom masturbator. It was complained about multiple times, but I found a new job before I found out what happened. -oh_look_a_fist

Crawling in a person's crawlspace with a full face respirator (superfund site). Turn from my stomach to my back, and in the process my mask ruptures a spider egg sac. Dozens (millions?) of fetal spiders land on my face. -deleted

I used to be the front-end manager at a supermarket. One night I had to head back to the deli for some reason.

As I made my way through the kitchen there was a bucket of rice on the floor that they used to make the rice dishes we served at the deli counter. To my surprise, two rats about the size of my hand jumped out of the rice and scurried under the oven. -BearJewKnowsBest

I’m a landscaper. Was weed-whacking in a backyard (my mouth was open for some reason) and turned right into a spider web. Spider went in my mouth and I spat it out onto the ground. 0/10 day for both me and the spider. -slept_on_the_gouda_

I used to work in hospitality. The senior chef there was the most arrogant, rude entitled SOB. One time a table of three hated his food & complaint. He assured the customers he'll cook them a new meal, he then proceeded to spit on the food before it went out. No one knew of this until he confessed to his colleague once he learnt from the waiter they ate all of the food, he was then seen on camera spitting in the meals. -Successful_Ranger_19

My first cockroach job as a pest control technician (exterminator) was one of the worse I’ve ever seen. My seasoned coworker pointed out that when people have severe roach problems, they tend to not have any hair on their face (no eyebrows/eyelashes/etc). When I went back, I noticed not a single family member had any kind of facial hair. Even the toddler had no eyelashes. Definitely still haunts me. -picklepotty121

I bent over to pick up a tool I dropped and a cow sh*t in my butt crack. -Bonhomme7h

Tattooed a lady. Small hummingbird on the shoulder. Finish up. “Go check it out, let me know if you want to keep it!” (Haw haw) “Oh thank you it looks gr-“ (passes out, I catch her and lower her gently to the floor while I begin ensuring she isn’t seizing, asking coworker to grab a popsicle, etc.)

She pees herself in the few seconds this is occurring in. Husband comes into booth to check on her, slips in pee, falls down. I’m struggling to keep it together so nobody feels embarrassed. She comes to after a second. Stands up. Not just pee. -Tsundoku_tt
