went thru many comments here and despite lots disagreement between people, I believe one thing people will all agree with is: in this game, individuals are much weaker than companies and much more vulnerable regardless.

company can never go bankrupt because of loosing one super star, but a worker and his/her family can be in a bad situation if company decides to do something to him/her. So the whatever negotiation between company and works can never be a fair game at any point.
