It's not ok to cross picket lines. Nope. That being said, creating a list of offenders and carrying out your own form of vigilante justice isn't exactly right either. To me, it just smacks of childishness. It seems like you're taking the meager power you get with a jumpseat to control and let it go do your head. Because really, the jumpseat is the only authority you wield over these guys, you can't really keep them from getting hired (you can try, but I doubt you'll be successful) and for what purpose, so one more pilot has to take a substandard job to pay the mortgage? You're not going to be scablist-ID'ing at the local supermarket to slash their tires. You're not doing anything more than inconveniencing them. If you really wanted to punish a jumpseater, let him on then from 10,000 to 10,000 lecture him continuously about how much of a bastard he is for scabbing if you have the juevos (which I doubt most of the posters do). If you want to punish those guys, lobby congress in order to create legislation that sentences scabs (I mean real scabs, not any of the others) to some sort of punishment for crossing a picket line. Do something productive, but don't be a child in how you handle adult problems. Children look for retribution, adults look for solutions.
