If your workplace gets bombarded with hundreds of emails saying you're a Nazi and threatening to bomb/shoot up the place your corpo will absolutely fire you just to make the headache go away.
It's a common ANTIFA terror tactic they use to unperson/debank people they don't like.
its honestly much more sad then that if you ask me, In another life I was close with someone who worked in HR for a decent sized "known" company
they told me that during hiring they will sometimes get calls from "friends"/acquaintances that have somehow learned the person was applying just to say and I quote
"you should not hire/employ this person they are, insert random negative adjective here lazy, prone to anger issues, bad communicator or really any other generic negative that is hard to disprove"
you dont have to get to over the top with it, its the straightforwardness of it that I guess has impact, anyway what the HR person told me was that if a call like that comes in its more or less a death notice especially if its still in the hiring process because as they told me "we are LOOKING for reasons to say no".
Those HR people live and die on the smallest things, multiple people calling to say they have a problem with employee X? They will just assume that multiple people would not make this up for no reason and think they are doing their job correctly by removing the "problem" and that is the end of their depth of thought on the issue.
During me2s height they told me one story of a guy getting fired because an ex of his called and said years ago he had made her feel uncomfortable in their relationship by yelling at her when they broke up or something like that and the guy was out THE SAME DAY.
Going to keep this random redditor in my prayers, by the Grace of God alone, we all go
