I highly doubt they'd support the rank and file for long if at all. In 97 they hadn't settled their contract yet so they were likely expecting driver's support if they striked.
They will honor our picket lines.. the pilots are more hard core Union than the average UPS union employee...
I don’t know the details about their tentative agreement... these pilots are pretty much well off they will not risk being labeled as a strike breaker, that would end their careers.
Also pretty sure there is wording in their contract about honoring everybody’s picket line, similar to ours.
I believe they could not strike..under some other federal labor agreement that prevents a labor stoppage.
