I (19F) work at a coffee shop, and one of my coworkers (let’s call him Coworker A) was rude and condescending to me when I first joined. I defended myself, and after that, he stopped being rude. However, he started telling everyone that I didn’t like him, even though I didn’t like him for good reason—because of how he treated me. I was polite to him, but not excessively nice.

Things took another turn when he came into work one day already high and was rude to me again. I asked him what the point of him coming in was if he was just going to be an ass, and he walked out, telling me to close the shop on my own. Since I wasn’t allowed to close by myself, I went to his friend (a coworker I’ll call Coworker B) and told her to report to our manager that Coworker A had left and that I couldn’t close alone. I also told Coworker B that Coworker A was on drugs and needed to let the manager know. Coworker B seemed hesitant, but I encouraged her to tell the truth. She later seemed upset and cried about it, and now I feel guilty for pushing her to do it.

Later that same day, a customer overheard Coworker A admitting he was under the influence at work and reported him to HR. Now, Coworker A is under investigation and could be suspended or fired. The issue is, many of my coworkers feel bad for him and are sympathetic, but I’m frustrated because I feel like he’s getting sympathy despite his rude and unprofessional behavior toward me.

AITA for pushing Coworker B to tell the truth to our manager and maybe getting him fired?
