Google uses medical leave to oust workers alleging discrimination (nbcnews.com)

“Unsatisfied, Cruz asked human resources to look deeper into the incident”

It sounds like someone made a rude comment. Cruz reported it. HR seems to have confirmed it happened / it was rude.

What is there to look into deeper? What did Cruz want and expect to happen? What am I missing?

His mistake was trusting HR to be on his side.
