Well, I've forwarded the ex-boss' e-mail to the police, the union and to the local member who supported a grant application from the company.
He had no way of knowing that I'd found a friend hanging. To be honest, I don't think he'd give a rats. The man is incapable of empathy.
I'm not sending anything back to him.
On my part, I'm trying to get on with it. I'm no longer having flashbacks to finding my friend dead and have finally found the energy to clean up a bit.
It's always surprising to discover how toxic a place has been only after you've left it.
