With dockworkers being put into place in a big way , it looks like a missed opportunity for those in favor of unionization.
As they increase in number and they gain seniority , they slowly start to realize that they have jacked up overtime rules , they do grunt work ( on the ice cold or blazing hot dirty dock ) , they are arbitrarily made part-time , they are paid less an hour than drivers , and there is no policy that I've seen as to when and how to become a driver.
In a unionizing effort why would you ignore these folks?
