When I first started delivering freight in the early seventies, I brought back a delivery becauseEspecially when a Scab (Strikebreaker) is someone who crosses a picket line to do the work of those on strike. That's what a Scab is and not a nonunion worker.
I remember back in the 80's Roadway dispatched me (I was a road driver calling in for instructions with an empty enroute back home) to pick up at one of their customers. When I arrived and saw they were on strike I called dispatch and was informed it was okay as other companies were crossing the picket line. I hung up and came on in with an empty trailer. Dispatch started to chew me out when I did that and I stopped him and said "you want me to call the Local about this?" Conversation was then over.
of a picket line. My boss told me the next day it was alright to cross it. So I stopped in front of the picket line and was approached by a striker. I told him what my boss said, and the striker told me: Son, you don't want to do that. Tell your boss we threatened you. They didn't threaten me but I told my boss they did. Not another word was said to me about that delivery. That striker gave me some very good advice about picket lines.
