I have made a formal complaint to my boss today against another employee who used aggressive behaviour towards me earlier in the week including an horrendous amount of swearing. There were 2 witnesses.
It was so bad I was unable to respond and removed myself from the situation to a different part of the office.
Said employee read an email I had written to our line manager saying that employee may be in trouble and that the bosses were involved. He went ballistic hence his behaviour and my actions. I personally feel he thinks I have reported him for something - I didn't do this. I verified questions I was asked but I did not report said employee.
I am actually quite scared, emotional and worried. I hope I have given enough to go on. I don't want to out myself.
