Ask HN: Is this an employee confidentiality breach?

This is from a friend:

"Unbeknownst to me, I was granted stock options back in January by my company but the VP gave the RSU letter to my coworker (not clear on why) and she's had it for 3 months. I don't go in the office much (work remotely) but that doesn't seem like a valid excuse for her to hold onto it and I've seen her multiple times since January. No one told me about the stock options...not my boss, the coworker, HR, etc. and I was unaware of the letter until my coworker randomly mentioned it, also that she read it. Not everyone in the company gets stock so it's not as if this is some generic form letter. I am really pissed off but not sure if this is a breach of confidentiality or just plain unprofessional."
