An example: I once had someone tell me to my face that I shouldn’t have an engineering job at all because no white men without a college degree should be “allowed” to. At work. However, this person was involved in ERGs and close with people in HR, so I didn’t have much choice but to just accept it and move on.
Another good example I’ve seen personally: employer hires a new CTO. He sets up the second phase of our interview process to be a phone call with him, and out of dozens of candidates he only allows Muslim candidates through this process. This was the clearest case of discrimination I have seen. When someone on my team speaks out about this, he’s fired and we are all scolded about racism being unacceptable.
This isn’t a social contract, it’s organized harassment and abuse by politically obsessed weirdos and it has no place in any professional environment.
Are you familiar with the Paradox of Tolerance (https://en.wikipedia.org/wiki/Paradox_of_tolerance)?
It is best understood as a social contract - in order for a group to function, people need to tolerate each other. People who don't obey that social contract are therefore not eligible for being in the group.
