No, it should not piss off any employer!

The equity that is offered to you to as part of your employment is remuneration for your efforts. The employer should not be upset at you for wanting to convert that to cash. It is true that the employer might not want their stock to go to outside parties. In that case, they should arrange for alternate arrangements (buybacks, employee-liquidity in funding rounds etc). But you are not doing anything inherently unethical to warrant any retaliation.

I completely agree with you, but this isn't mutually exclusive with facing retaliation (in terms of internal politics, for instance.)

That's more to the point I was getting at. There's the legal situation, and then the political one. Selling shares in a private company could raise some red flags from management thinking an employee wants to cash out and bail, management worried about the perception of the company's health (internally and externally), management concerns about loss of control, etc.

All reasons why managers might make life difficult for said employee after the fact.
