Former horrid coworker now reports to me

An employee who endured years of torment from a toxic coworker suddenly finds herself as that person’s direct boss. After all the drama—from slander and sabotage to fantasies of payback—things unfolded in the most unexpected way.

When HR forced “Mary” the one who once drove her to switch jobs early onto her team, the OP initially dreamed of retaliation. But that first meeting changed everything, with an unforeseen apology and a choice to take the higher ground over abusing power.

‘Former horrid coworker now reports to me’

It all started years ago when the OP worked alongside a deeply spiteful colleague named Mary:

Several years ago I worked with the most spiteful, troublemaking woman ("Mary"). She and I applied for the same promotion and she got it. I was OK with not getting...

She was not in my chain of command but she seemed to think her promotion gave her the right to treat me badly. She would make snide comments about me...

She would try to assign work to me. When I'd refuse, she'd run to our mutual boss and complain until she got her way and I'd have to take on...

Eventually, I was promoted to another department. In the days before I went to my new job, it was apparent that someone was sabotaging my work - data was changed...

Of course, I suspected her, but, again, had no proof. It all came to a head when she announced to the entire office that I was actually the one who...

It got so bad that I made arrangements to go to my new job earlier than originally planned. For the next several years, Mary and I would have to work...

After multiple promotions, the OP became department director—then got blindsided with Mary as a direct report:

During that time, I received several promotions and ended up as the director of my department. There are about 50 people in my department and I mainly have contact with...

I guess I'm known as the one to give problem employees to (I either get them to "shape up or ship out") but I was very surprised when HR approached...

My initial reaction was "hell no!" I really felt I couldn't be impartial and give her a fair chance. But I pretty much wasn't given a choice. What's worse, I...

After resigning myself to having to take her on, I started dreaming of how I would exact my revenge. There were so many possibilities; I was almost giddy with anticipation....

I called her into my office to give her my "come to Jesus" message. She came in with the most scared look on her face. I thought she was going...

She replied meekly "I guess it's karma". You could have knocked me over with a feather. I knew exactly what she meant, but I wanted to hear her say it....

She then proceeded to apologize for everything she'd done to me, including spreading lies and doing the sabotaging herself. I was about ready to admit defeat in the revenge game,...

I told her ever so calmly "You know that you could be fired for that." I let that sink in until I saw the beads of sweat on her forehead....

You will not be able to blame me for what happens to you because it will be up to you to succeed or fail." It felt so much better than...

Not because she's going to be fired - she really has improved a great deal - but because being nice to me is so hard for her, I don't think...

This story highlights the power of choosing the high road in toxic workplace conflicts. The OP suffered heavy bullying but, when handed authority, opted for fairness—forcing Mary to own her behavior and performance.

Mary’s apology shows she recognized her mistakes, albeit late. By not firing her outright and offering a real shot, the OP demonstrated mature leadership that fosters a healthier work culture.

As noted in Harvard Business Review on managing former peers: “Great leaders turn adversaries into allies by focusing on performance over past grudges.” The OP nailed that, turning a poisonous situation into growth for both.

Still, stay vigilant—real change is rare overnight. Monitor closely to ensure Mary isn’t repeating old patterns with others, and acknowledge improvements to reinforce positive shifts.

Take a look at the comments from fellow users:

Online users overwhelmingly praised the OP for her mature handling and the subtle karma payoff.

Many hailed her as an outstanding leader and the “revenge” through kindness:

zippy72 - Be careful. Because I very much doubt she's a reformed character; she's almost certainly doing the same things again to try and undermine you.

Other takes were humorous or firmer:

PhilMeUpBaby - No. She needs to be fired. Immediately. By sabotaging one person she's actually been sabotaging the entire company (ie modifying data). Data doesn't die.

Data lasts forever. There could be something that she changed years ago that could still come back to cause harm in the future. And, for that, she should have been...

Nobody_asked_me1990 - Honestly this type of revenge seems to have worked out better than any revenge you could plan, and it speaks to your character. Good job, I envy you....

NightHeart21689 - Getting her to admit what she did wrong was absolutely sweet. Horrible people like Mary rarely admit when they're wrong.

Kinteokolomee - Can you update me when she goes? I like to apply for her job. . I heard her boss is quite a decent human being

pepperpat64 - Do you not track changes on shared files? That will tell you who accessed them and what they did.

FallenRadish - The true "Petty Revenge" is the lack of paragraph breaks.

The OP turned a grudge-filled scenario into a masterclass in leadership, picking kindness and accountability over direct payback. Mary faced consequences through her own apology and the pressure to step up, while the OP solidified her own integrity.

Whether Mary stays or goes, this proves karma often arrives in the subtlest forms. Ever dealt with something similar at work—revenge or forgiveness, which felt more satisfying? Tell us your story!
