There were several picket line crossers in my feeder department as well. A majority of the other drivers refused to communicate with them afterward and don't to this day. There were probably some scattered examples of retribution by a few individuals. The line crossers had to double check their couples if they left their sight. I don't know about PC, but feeder drivers have long memories. I walked the picket lines for over a week, then I found some work the union hall fixed me up with for a couple of days, then it was settled.
