Basically none of it. RSUs at public companies are as good as cash that just happens to be pre-invested. The tax implications are very simple (they're just regular income like getting paid in cash), and so are your legal rights (you're not much different from anyone who bought a share on the stock exchange). You should risk-adjust their value like any investment, but there's are very few if any sneaky things that can happen to pull the rug entirely.

I do wonder how much of this applies to RSUs granted by public corps
