Goodwill Industries

I've been a good worker and got treated poorly then got chosen over a lazy employee, I've always shown up on time and early at times then I get fired out of nowhere because I "slammed" a door at someone who was threatening me then getting in my face, I told hr that I wasn't comfortable and safe in my work environment then few days later I got called to be fired, I don't know what I did to deserve this but I've been working there since August.
