People do shady stuff all the time. That's kind of par for the course when it comes to any human endeavor -- but none more so than in the business of money-making. Indeed, when there's cash on the line, seemingly upstanding people can become all-too-ready to cut corners and "bend" the rules when it means a juicier bottom line.

And, usually, at the expense of the customers, employees or people and places around them. Down below are the dirtiest secrets from insiders who saw a little too much.

Worked at Domino's in college. Our franchisee made it a fireable offense to call in sick. If you missed a scheduled shift, it would be considered quitting, and you wouldn't get put on the schedule ever again. As a result, workers would come in to work INCREDIBLY ill and still make your food. I once witnessed a coworker begin to make a pizza, stop to go puke in the bathroom, then continue making the pizza.

Dupont killed off an endangered species in an area they wanted to expand. Then they laid off some folks who knew they were endangered, and magically the epa inspector didnt find anything, because they had buried up the pits and holes where the frogs had died.

When diesel fuel gets spilled in working water front they just spread dish soap. This sinks the fuel to the bottom, where it can't be cleaned up, avoiding the rainbow slick, 10k fine, and a real clean up.

This is my best story, I was 18 and a pushover at the time, wasn’t going to argue since I just started working there:

At Staples (in Canada), we ran out of pencil crayons during back to school season, which was not good for business; parents want to do one-stop shopping for school. So one of the managers took me to the Wal-Mart at the other end of the shopping centre, and we loaded up 2 carts with ALL of their pencil crayons.

It gets worse. To eliminate any suspicion and prevent the Wal-Mart managers from stopping us, we told the cashiers we were on a mission trip to Africa and that these were supplies for poor schools over there. They believed it, we took them all, stocked the shelves at Staples and resold them.

I worked at this awful pet store that sold dogs. We all knew the prices of all the dogs by heart but if someone asked we had to pretend not to know, bring the dog out to them to play with(even if they specifically ask you not to)so they get attached. Meanwhile I'm in the back with my thumb up my a** pretending to look up the price. Then when they're all nice and bonded with the dog I'd have to come out to tell them that instead of the $300ish they were expecting, it would be more like $2,500. Queue tears.

Lots of tears. There was all this complete bs we had to tell them to justify the price including that the dogs were registered. Well I had a customer come back absolutely furious that the dog wasn't actually registered. Turns out what management meant(but didn't EVER say to us) was that the dogs were register-able. That's just one example of a whole lot of s**t I put up with there. I'm a pretty honest person as guilt really gets to me more than normal I think and all that intense lying through my teeth to good people made me extremely depressed and I quit after only 3 months.

I worked at a “luxury” movie theatre for 3 years. Complete with service to your seat, oversized recliner seats, pillows and blankets. The pillows and blankets were never washed. Ever. But the break room was stocked with brand new ones. Always ask for a new blanket.

I worked for the northwest company in northern Canada. The Inuk art that they sell for hundreds or thousands of dollars they buy for $10-20 from the artist. I asked a manager why, he said it’s because they’re poor anyway. I quit that evil company the next week.

Ruby Falls is fake. Their waterfall is pumped in. It's artificial. The formations are paint and plastic and styrofoam or occasionally purchases from other caves halfway across the country. They lie about the height of the falls. Like not a little exaggeration, they claim it's almost twice as high as it is. Most of the stories your tour guides tell you are made up. Unless they have gray hair their funny quips about past tours are mostly bs. The employees are not told any of this and have to piece it together on their own. A lot of management legitimately doesn't know. The tour guides know and don't care, the ones that do care quit. They threaten to sue employees who ever reveal any of this EVEN TO FELLOW EMPLOYEES!

Hotel I use to work for payed off a surveyor not to tell people that they destroyed a ton native American artifacts when they built. Pottery, bones, you name it they bulldozed over it.

Current PetSmart employee. The amount of "quiet" (dead) fish we have to throw out by the end of a single DAY is ridiculous. I don't know how it isn't alarming to customers, because we're told to do it right in front of them. Also, I don't understand why it isn't allowed to socialize the animals. Nobody wants a hamster or any pet that is going to bite.

Most dairy coolers in stores are riddled with mold.

I used to work for a food distributor and I was forced to work when sick with out gloves or masks because they ran out.

Went to an Aveda beauty school. Every year Aveda does a big recycling cap program, since most plastic caps cannot be recycled. We collected caps for a month, and our clients were really excited to be helping the environment. After the promo was done the instructors made us grab 3-4 garbage bags of caps each...and we threw them in the dumpster of the building next door. We didn't even use our own trash. Probably because Aveda can take away their franchising rights if they find any infractions. Also Aveda is owned by Estee Lauder so there is literally nothing natural about them. And they test on animals.

Female co-worker filed a complaint because a male co-worker slapped her a**. I watched management have him sign his paperwork for a “written warning” and then I watched management shred it while the female co-worker was at lunch. I worked in HR for them at the time. I can confirm they made no formal documentation of anything that happened that day. They shredded the only paperwork that even acknowledged it happened.

Worked in the kitchen at a Wetherspoons (pub chain in UK). If anything went out of date, we simply changed the day dot on it so it now says it goes out of date tomorrow instead. If something fresh didn't sell well but we already had lots of it prepared (this would happen with steaks and fish mostly) the dates would get repeatedly changed until it went brown/stank and then it would get put on 'special'. Manager's bonuses were, in part, based on wastage; lower wastage=higher bonus. Also we got pretty much everything pre-portioned, frozen and so at least part if not all of your meal will be microwaved. In general the later you come in, the more kitchen equipment we have turned off and cleaned so more of it goes in the mikes. Send back your food because its cold? That's going in the microwave. That job seriously broadened my mind to what exactly you can cook using microwaves alone. We also didn't get breaks. They would even tailor shift lengths so that you would get the shortest legal length breaks (that we would get shouted at for taking anyway). For example, a 5 hour shift gives you 15 minutes break but a 4:45 shift gives you no break, guess which one they give you.

I worked for a chicken restaurant. At one point we were so infested with cockroaches it was normal to see about 20 a day. We (The management and supervisor staff) begged the manager to shut down the store to clean. Instead we never ever stopped and were required to come in on the weekends to clean around everything. We also were required to call cockroaches "friends" so we wouldn't let the customer know that we were infested. On more than one occasion we would feel them crawling on us and we were told we weren't allowed to react or we would be written up. Thankfully we got shut down by the health department and corporate took over the store and turned it around.

Worked at Red Robin was constantly forced to buy tube meat from Walmart and sell it as Gourmet. Had to sneak it in the back so nobody would connect the dots.

Glassdoor.com Does remove job reviews and DOES let employers choose which ones get shown first!

At a movie theater where I used to work, at the end of the night, we would collect all the unsold popcorn and stuff it into these enormous yellow trash bags. The next morning, yesterday's popcorn was the first to go in the warmer. My boss said that popcorn was fine to reheat and serve for up to a week. We never dated the bags, though (bags that we were not allowed to throw away. We reused them all the time) so there was literally no way to know how old the popcorn was. Not as horrifying as some stuff here, but I thought it was kinda gross.

At a certain chicken establishment, we had deep friers that you put chicken into, locked them up, waited on the machines timer and pulled them out. It was 3 mins and 30 seconds long. In rushes when we were low on chicken, they made us open the machines up earlier before they were fully cooked by sometimes a full minute... I didn't work there that long.

I worked in a coffee shop where they would buy individually packaged muffins in bulk, like the kind you see in convenience stores. They would then have us remove them from their packaging and wrap them in saran wrap, and sell them as homemade for over twice the price as what they sold literally next door at the gas station. I always enjoyed the compliments I got for my baking skills.

This is way more lighthearted than most, but here it goes. I used to work at a fast casual burger place with a secret recipe BBQ sauce. The secret ingredient was Root Beer syrup.

Walmart distribution center had a week long orientation. For about 2 days of that orientation they gave us reasons why unions are bad and have no place in the company . They told us we would be terminated if we tried to unionize. They pretty much fed us propaganda materials and treated us like kids. They made us repeat that we understood the situation and the consequences of attempted unionization.

I "managed" a food joint at a six flags when I was 16. But a 16yo running a food establishment is not even the worst part. We literally watered down the nacho cheese about (50/50), I grilled chicken for 10 hours a day on the same grill without time to clean it so by the end of the day there was a quarter inch of gunk built up, I had new crew members everyday who had never worked there before, my managers would take their breaks when we needed to close but we couldn't leave until they checked our work, so we would just sit for a good 30mins before we could go home. I ended up getting fired because in accidentally bumped a HIDDEN SECURITY CAMERA while cleaning in the back room.

I still have copies of emails from our Gamestop district manager directing us to sell through all our pre orders of GTA4 instead of holding them for the customers that reserved them because he got a commission on total numbers sold.

Worked at McDonals as a teenager in the kitchen there. As a cook we were trained that whenever we hear a timer go off on a tray in the patty warmer we press the button to reset and do nothing else. When I was training to be a manager we were taught that the timers were the recommended safe time for a patty to sit in the warmer and all the pattys in the tray that timed out should be thrown away. As a cook we would often have trays that had their timers reset 5+ times in a row before the pattys were served from them.

I worked at NASA as a contractor for 2 years. 90% of the computing hardware was very antiquated and out of date. I saw a lot of Dell computers from the mid 2000s still being used, yes even pre-thin-style monitors, that beige or off-white color. They are pretty underfunded and spend most of their money on more advanced hardware like supercomputers, large servers, etc. But the basic hardware is really out of date. In fact, the whole place looked like a museum of the 1990s...the architecture, the dress styles, the lighting, carpet, and so on. It was very strange, almost eerie.

If you ordered any vodka; Grey Goose Belvedere Titos Ketel one, etc You are getting Blue Ice vodka. Owner of the bar would pour cheap vodka into those bottles. I refused to do it myself, so he would do it. I made phenomenal money there, 350-500 a shift so i never said s**t about it. After i quit i let people know. Was shut down 3 months after
