Not enough sick time to avoid them when I was a 757 FO. My FO seniority lined up perfect with scab CA seniority. If I was Native American, I would be called "flys with scabs."

A scab is someone who crosses a legal strike or accepts less than union wages.

The main thing to do is not be their friend. Kinda a sterile cockpit inflight and no hanging out at the layover.
