Yes, with two exceptions.

First, new hires are required to pay the initiation fee and dues (or association fee if they choose not to be a member.) I don't know which is the norm in the airline industry, but it is (was) good that FAPA did not require dues payments from probationary pilots.

Secondly, the RAH contract specifically states that pilots can be fired without cause. Management actually did fire 125 probationary Saab guys back in 2001 rather than incur the training costs of furloughing in seniority order.

Granted, those are pretty significant exceptions, but beyond that, it is pretty much the same.

That being said, I reiterate that a back to work agreement post strike is outside the scope of the probation language in the contract. While I am no longer at RAH, when I was there I worked pretty closely with PG & co. I have no reason to believe they would even consider an agreement that did not include reinstatement of any probationary pilots fired for not crossing the line.

So in answer to the OP: No, under no circumstances should you ever cross a picket line for any reason. I cannot say with absolute certainty you will be reinstated through a back to work agreement if taken hostage, but based on my knowledge of the EXCO at RAH I am as close to absolutely certain as I can get. But crossing the line and keeping your job would be infinitely worse than honoring the line and losing it.

But also keep in mind, before you show up for class, that most everyone who is at RAH now is trying to get out. I was a very senior captain there until I bailed a year ago. I took the first offer I got, with a 60% pay cut, and have not for a minute regretted my decision.

There are rumors of furlough where I am now and my head will certainly be on the block if that happens. I would rather be furloughed from here than be a senior captain there. YMMV
