I'm torn between agreeing that employees should carefully read their options agreement and believing that there are some things in life that are wrong with no grey area and stealing shares people have earned is wrong.
But this? It isn't so clear.
But you could, for instance, join together with other employees whose interests are more aligned with yours and join a union.
That is if there were any unions in the IT field.. and if they weren't nearly universally despised due to the omnipresent anti-union propaganda in the US.
