Nine women share their pettiest workplace revenge stories. Some are completely unhinged.

Who among us hasn't daydreamed about a petty act of revenge after your company denied another pay rise request? Or a coworker stole credit for something you did?

It turns out, some people don't just dream. They act.

From micro-acts of pettiness to full-blown chaos, workplace revenge can take many forms. A well-timed unsubscribe. A suspiciously missing coffee order. A single cracked egg hidden in the depths of the office fridge (true story).

They're the tiny victories that, some say, make surviving a toxic boss or an entitled colleague just a little bit easier, and a lot more satisfying.

Here, nine women share the pettiest act of workplace revenge they actually pulled off — ranging from the small, harmless jabs to full-scale sabotage missions.

Read them, wince, and maybe take notes (just in case you ever need them).

They start small.

"My boss doesn't acknowledge my emails or respond, so I keep all emails I send him in a separate inbox and no longer respond to any of his emails," one woman shared. "If he mentions something in person, I just say I've been busy and haven't seen his emails yet."

Another decided to grab what she could before leaving.

"I downloaded their entire Google Drive of resources," added a second.

A third woman got her revenge through her protective father.

For some, revenge was a team effort.

"I organised everyone to quit at the same time so they would have no workers and would be scrambling to find new people."

Others found smaller ways to cause trouble on their way out the door.

"I worked on a remote cattle station and the whole family were a complete nightmare. I cried every night of my three-week stint. So when I left, I left every gate I drove through on the property open. If you know, you know that you NEVER leave a gate open."

Some acts were so subtle they went unnoticed for months. But, when they were discovered, the chaos they caused was unforgettable.

"I cracked an egg at the back of the work fridge. The fridge was always full and infamously disgusting, so it was well hidden. I bumped into someone from that workplace way, way later on and I joked about the fridge. She told me they found a rotten egg that stunk out the office a few months after I left, and it's been clean ever since. They should thank me honestly."

Others required a bit more, well, physicality.

"Years and years ago — in the brutal Hunger Games world of retail, I worked with a girl who kept stealing my sales," shared a seventh woman.

"She would put them through under her staff number when I wasn't looking, or take over in the change-room — ordering me to clean something, or race me to the customer."

The anonymous woman explained that she and her co-workers were given a bonus on sales over certain amounts, or if they made a daily budget, meaning this girl was taking incentives away from her.

"She was also senior to me, so I couldn't really call her out in front of the customer. One evening she was going on a date and had forgot some make-up, and I offered to lend mine and she responded with something mean like, 'I only use good brands.' I snapped.

"When she went on her toilet break, I took her toothbrush, which she kept at work for some reason and rubbed it on the mop we use for cleaning the store. I'm not 100 per cent proud of it."

It was an act of revenge echoed by another submission.

"I rubbed my butt on their keyboard. I have done this to multiple people."

It might seem like things can't get much worse than this, but for anyone who has been a target of spam emails, this last one might just be the most sinister.

"In the days before spam filters, I signed my male boss up to hundreds of email newsletters," wrote one disgruntled worker. "I jammed up his work inbox with Horse Weekly, Farm Life, Christian News, Pregnancy Daily and Baby Mag and so much more.

"It was hard to unsubscribe to them individually. He was vocal for weeks and got so upset. In the end, he had to get a new email account. Every single minute was deeply satisfying."

From butt-rubbing keyboards to inbox sabotage, these stories are reminders of the small, messy ways people try to reclaim a sense of power in workplaces that leave them feeling powerless.
