I have information that could get someone sacked, or at least force them to resign.
This person is a vicious bully and deserves to lose their job. Over the last 2 years they have taken great delight in getting rid of people they didn't like by making their working life hell.
This person is very senior in the org and everyone is scared of them. The union have recently raised a grievance, which many managers have backed.
I have information that would support the grievance and also raise questions as to this persons decision making and integrity.
The dimlemma I have is that I am not sure whether the information would be enough to get them the sack - the person is very good at talking their way out of things.
If I came forward, it would be obvious the information had come from me so there would be no point in asking to remain annoymous.
If the person didn't get the sack they would make my working life hell and I would be forced to leave. If I don't do anything, they will be able to go on behaving disgracefully and making other people's life hell.
There are people higher up in the org that I feel should be speaking out and would have more damning evidence than me but they won't because they are too scared.
So WWYD?
