I came into work today and apparently a coworker walked out during his shift yesterday. Fine, but now he's saying that he's going to sue us because he thinks walking out doesn't count as quitting. He threatened one of my employees and carries a gun in his car, something he brags about. I have minors working and if he comes in today, I will have to call the police. Dude was a nightmare to work with and now I have to worry for everyone's safety, all because he wanted a break and didn't get one.
