I've now read the original report linked above. I recommend others do.
It is completely bullshit.
Full of he said/she said. 'complainant claims colleague said xyz, colleague claims they said abc, we decided to believe complainant' over and over.
It is entirely probable that everyone immediately perceived the tim as male and hence ridiculous to talk of 'outing' a legal, biological man, with male status and male name on his ID documents.
Some of the findings are outrageous. Colleagues having a private conversation with no references to the tim, are overheard and assumed to be making references to him?
It's all nuts. TIMs should have the same rights as every other employee, but characterising things as bullying needs actual evidence.
The only thing to give me pause was the claim that someone described him as evil, which is unacceptable if it happened.
