While a strike can pose short-term challenges, both AT&T and Verizon have trained replacement workers to fill in for union roles, unions were "fashionable" and "viable" during the 1930's through 1960's but became obsolete models because they retarded competitive growth in the non-unionized emerging global market place. Today, it's Capitalism at it's finest, in which unions are non-competitive, few benefits associated with the 30 % membership, and if you can't think for yourself you must let others decide your fate.
But are there times when our fears are warranted, or perhaps trying to warn us of potential bad outcomes? Do you let fear stop you from doing anything, or do you push it aside and take the plunge anyway? The decision is all yours, to make.
