HR is designed to protect the company, from *YOU*. NOT you from bad actors, including clients.
Never get chummy with coworkers. At least one of them thrives on gossip/drama and will spread rumors about you.
@sardonicsmile HR is there for company. Because it is protecting the company from lawsuits(you).
This is like calling police on government.
What they will say
@sardonicsmile Its always a good idea to make HR ppl your friends
