It’s tough when managers think criticism is the only form of communication, especially when it’s more destructive than constructive.

Little did one bad boss know, his dismissive attitude would soon lead him to a flood of unsolicited emails, courtesy of someone who’d had enough.

As one does.

Read on for the full story.

Signed my boss up for every email list I could fine

Back in the early 2000s, I had a manager that would often be a jerk to many of his employees, including me.

He loved to tell people that they should be happy to have a job, gave no constructive feedback, it was all just how bad we were.

His poor feedback style was reflected in his performance reviews.

When I got my review for the year, he had given me a 1 of 5.

When I asked his boss to review my review, his boss literally said “What the heck,” as he had talked to lots of my internal customers.

The boss’ boss was much more kind and objective.

His boss actually gave me a 4.7 or something out of 5 on the re-review because he knew the changes I had helped the team make.

Regardless, the employee was going to make their boss pay for their cruel review.

Not long after the review, I would be on the internet and anytime that a website would ask me to sign up for their email (long before you had to opt-in), I would put his work email into the field.

I did this for a few weeks and then moved on with my life because I had a million other things to do.

When they check in later, their boss’ inbox is flooded.

A year later, I was helping him with something on his computer and made a comment about having 10,000 unread emails.

He made a comment about getting on some spam lists and now getting hundreds of emails a day weren’t work related.

When I left his office after that, I suddenly remembered signing him up for email lists and smiled back to my desk.

The unread emails started piling up, and so did the poetic justice.

What did Reddit think?

Before the internet, it was even easier to make a bad boss look bad.

This mistreated employee got back at their boss in the most personal way they knew how.

While one friend opted for physical pranks, this friend decided to digitally annihilate his opponent.

This redditor hopes the author’s bad boss starts to miss actual work-related emails with all the junk.

Ultimately, the manager’s inbox became a reflection of his management style—cluttered, overwhelming, and completely avoidable.

Petty but effective.
