Only if the issue is with that individual employee. In this case, that obviously isn’t the case. Ignoring a systemic problem in your company solves nothing.
Don't know if that's true. The big goal is to avoid federal lawsuits and other scandals. If the can can be kicked down the road for a few more years, fine! Uber only blew up because Susan Fowler was better connected than most, and you'd like to know how much the scandal affected the company. Uber is fine, Kalanick is fine, a few HR drones lost their jobs, business as usual.
