I would be willing to bet money that you mouthed off to a physician or a senior nurse like that, and that’s what actually got you fired. You are so incredibly lucky to have a union that was willing to stand up for you the way they did.

Seeing opportunities to learn about other people and foster relationships as useless is just dickish. It’s not cool, it’s not cute, and no one likes that kind of behavior. I’m very heavily introverted, have social anxiety, depression, and ADHD; and it takes me a long time to warm up to other people. I have never once been fired or even reprimanded for anything at work, much less the way I speak to people, because I approach conversations with a warm tone and a willingness to engage with and learn about the other person. You need some help man. Please take this opportunity to engage in some self-improvement because you are setting yourself up to be miserable for the rest of your life.
