I've been meaning to provide an update on this situation, but have taken a bit of an unintentional break from the interwebz lately.
They fired the guy a few weeks ago!!!
Even though Florida is a state in which you don't need to give someone a reason they're being fired, also known as a Right-to-Work state, they got him on a technicality. I don't know the details exactly, but from what I understand, he was written up for excessive tardiness, and then one day he came in like 15 minutes late again and they let him go. I came in that day right after he was sent home. I also heard that there were multiple calls to corporate about him. It wasn't just me, but there were REAL customers who called. He was progressively looking worse, and worse, and worse in those last couple weeks he was there.
There was a noticeable collective sigh-of-relief that was felt after he was fired. I honestly can't believe he lasted there as long as he did. I have thought about reaching out to see how he's doing, but I realized that would be somewhat disingenuous of me as I let my voice be heard about how he is not safe to have employed.
I've seen some shit in my day, but I have never worked with anyone like him.
