I was almost written up for an “offensive” conversation on concealed carry I had at work with a machinist who made his own guns. It was in the lunchroom at lunchtime and it was overheard by the HR manager who was “offended.” I was warned by my boss, the VP, not to talk about guns at work as it was “offensive” to some people.
If being “offended” is the criteria, God help us all.
I would have asked for a list of all the offensive words and phrases not allowed to “better understand” what is allowed and not allowed.
They better be careful. After all, you may be offended but someone’s conversation. Who decides what is acceptable? That could get quite interesting.
Tell them "Oh, I'm ever so sorry my conversation offended you. So, apparently it is company policy to put a halt to anything that anyone finds offensive in the workplace? Great. You're fascist anti-free speech rules are offensive to me. I expect they'll be halted immediately, correct? After all, you're not discriminating against me, are you?"
I'd want to file an eavesdropping grievance. What gives someone the right to listen in and object to the content of a private conversation which is not directed at them, and which isn't loud to the point of unwanted public announcement?
