I was recently fired from my job in Texas for making a joke to a coworker that they claimed made them uncomfortable. This was really surprising to me because we had a friendly rapport and often joked around with each other. To make matters worse, I have a screenshot of them saying something very similar to me in the past. I never intended to make anyone feel uncomfortable, and this whole situation has left me feeling confused and hurt. It feels like I was punished for something that was part of our normal interactions. I'm wondering if I have any grounds for a case against the company, but I've heard that big companies often have policies in place that make it hard to fight back. I'm still trying to process everything and figure out what my next steps should be.
