Not in principle.
A fair negotiation is not possible if one side can simply divide and conquer.
What I have found, from working both sides of the issue is that the newest techniques involve continuously changing your managers and management chains. This works particularly well if you have an organization where many people work from home or the road. This does not allow folks to network or become close.
As an example, the team that was told today that their last day would be April 27 was spread out in 8 states. Only two knew each other and the rest had only met twice, that because I called two design meetings so everyone could actually get together. Those 10 people represented right at 200 years of technical experience and a total of 24 degrees and 7 patents.
They also generated between $800,000-$1,000,000 in taxable earning power that is going to be taking a rest.
