IMO one thing I think should be made into law is that if a company grants unvested equity, everything granted will automatically vest when you get laid off.
If you decide to quit before they vest, I understand that those grants should be forfeited. If you get fired for not doing your job, I also get forfeiting them.
But if the company lays you off, that's on their side, so I think the opposite (automatic vesting) should be guaranteed by law.
