I know it can be hard to prove, but I have documented quite a few months where I have raised concerns about an individual. 2 weeks back I was accosted as I left work. I raised it up to my manager as soon as I got back to work. After a “thorough investigation” I was basically told if I mess up at all I will be fired. Today I come in and there is still something going on, and I have another meeting with HR in the morning, this supposedly about an infraction that is never enforced. It literally happens every day on the shift before me and nothing is ever done about it. I feel as if they are retaliating against me for speaking up. Not sure if this would even begin to meet the criteria. I am already looking for another job, but it's tough this time of year.
