Would you rather forfeit 100% of unvested shares? Because that's what you signed up for.

The point is, you're getting shares for 16 weeks + ${years_employment * 2} additional weeks, and you don't have to work those weeks. It's comp that, according to the terms you agreed to when you accepted the job, you are not entitled to. You're getting it as an unearned parting gift.

Yes, it sucks to be laid off. But it sucks a little less if you get a parting gift that for many of the more senior folks will run into six figures.

Would you rather have that parting gift or not? Because some companies don't give you one when when they lay you off.
