HR works for the corp, strictly in the corporations interests. Even if the narrative you’re describing is true (I don’t know either), it’s only a coincidental[0] point, not The Reason for BtO policies.

> I have talked with HR

HR, in general, is not a reliable source on anything other than what the company for whom they work wants you, as a potentially unreliable production input, to believe in order to keep you maximally aligned with the interests of the corporate owners as relayed through management.

I heard the same. I also asked someone who is in management. They said that they were getting a lot of feedback from exit interviews from employees with > one year of tenure who left. Many complain of feeling disconnected from their team or not know what to do.
