One of our service techs is a legit flat earther. He has been working with the company for a couple years but I have only been managing the department and him for a few months. He came in for a training and while we were all at lunch went into a while flat earth rant trying to convince us that the earth was flat, gravity wasn't real the moon and sun were the same size and a bunch of other wild shit. At first I thought he was joking and just putting on a show but he was dead serious, dude makes YouTube videos about it and everything.
We are hiring for a new tech and got a bunch of qualified applicants. I decided to let this guy go and hire someone a little more mentally stable that I can trust not to make our company look like idiots to our customers. He was a decent Tech but nowhere near our best and I just feel when can get someone in that position that is a much better fit.
