“Did it work?”
Two events caused me to never speak to any employees I didn’t already know. A black technician reported me for incorrect political thinking. The manager of HR told me I should never speak to him again. He was dead serious that this was an actionable charge. A woman accused me of sexual harassments, not for herself, but for a going-away roast of another woman. That woman said she was not harassed, but the standard is, if an uninvolved third party believes it’s harassment, then, it is.
I worked briefly for a spinoff from ITT. They had a rule that there could be no non-work related conversations. At lunch, I had a discussion with a machinist who made his own guns. The HR manager overheard it and wanted us both written up. I was called into the VP’s office and pointed out that we were at lunch. He said, which is on company property. He managed to stop the write-up because I dealt directly with the customer and it would have been bad politics.
So, yes, you’re right about the speech.
Yes, the workplace has gone completely mercenary and the same people who think they're going to force you to embrace their illness can't grasp that you'll simply have nothing to do with them. Smart women are already complaining that other women ruined the workplace for them because no man will talk to them except for work only, no mentoring, and only with witnesses present.
Threaten the teacher and you'll learn nothing.
