I put the M in EMTLife
How do federal regulators keep anyone from dying?
How is AMR picking up extra business putting money in Gold Cross' bank account?
Federal regulators and mediators can require workers continue to work, as if they weren't striking, during ongoing negotiations. There are laws that regulate cooling off periods and most parts of a job action.
Scab workers allow the company to continue to function, albeit in a diminished capacity, during a strike. The company would not be able to funds ion, and the executives would face increased pressure, without scab workers.
Again, I'm not here to argue whether any side is right or wrong. Scab workers and companies undermine the efforts of the workers on strike. I couldn't do it, but clearly others are willing to cross the picket line.
