Sorry, but strikes are sometimes necessary, as are the threat of strikes.
Yes, they are destructive to all concerned, but so what?
If two parties negotiate but cannot reach a settlement, then either the management withdraws the pay (ie fires everyone) or the workers withdraw their labor (strike or quit).
And if you think management is voluntarily going to give a larger slice of the pie to employees without some form of pressure then I have a bridge to sell you.
And for those who talk about AWA's, look up the meaning of the term "assymettry of bargaining power"
