And actually, it isn’t part of your job to just blithely accept death threats, and there may be legal grounds to go after your employer for insisting you tolerate them. Most certainly there would be epic levels of liability for your employer if you ever were harmed because of one and they were found to have that sort of attitude, official policy or not.
My mom is currently a manager in an IRS taxpayer help line unit. This happens weekly. As soon as someone gets hostile at all, the IRS rep clicks one mouse button, engages recording of call as well as popping up a notice on his/her supervisors computer that allows them to join the call.
The FBI does not smile on threats of violence to IRS buildings.
Working for an insurance company, I had much the same thing happen. Of course, this was after speaking for about five minutes about the guy’s piece-of-excrement policy, as part of which he’d confirmed his identity and address.
An address 890 kilometres away, but an address nonetheless.
So a quick call to the filth local to him was in order. They said that they’d send someone out to speak to the guy.
He called back an hour later, incredibly indignant that we’d he’d just been visited by the cops… and again threatened to come “down there” and shoot everyone for my daring to get the police involved.
So that got immediately followed by another brief chat with Moonee Ponds’ finest. He didn’t call back again.
