I am talking best employees. People who will find good job no matter what. People you need to keep because they are actually the ones who make the show going.

I am talking best employees. People who will find good job no matter what. People you need to keep because they are actually the ones who make the show going. You got hired thinking you will get some amount of money (salary + shares) now those shares are worth little even before they got vested. So you cut your loss and get hired at some other place that will give you more of your comp in form of salary than shares because you feel burned.
