My understanding is that TSA didn't agree upon the scope clause, per se. Management decided it was lucrative to take up AA flying and as such they kinda of got stuck with the 50 seat restriction. If TSA stopped flying for AA, they could fly 70 seaters all day.
The company then saw the chance to fly 70 seaters for UA and created the alter-ego to do that. So far, so good. The problem, as I understand it, is that TSA offered TSA pilots the option to fly the 70 seaters but wanted to pay sub standard wages. Instead of taking this chance and further debasing pilot status and proving to another management that we will do ANYTHING to fly, the vast majority of them said "NO". Some went over there and they are the SCABS in the highest sense of the word.
In time GoJet hired off the street. I understand the "you gotta eat", but it isn't that cut and dry because when GoJet was in its formation and through the first couple years, everyone was hiring. Why go to GoJet? And furthermore, flying isn't the only way to make money, especially in the short term, which is all it would take if there weren't scabs.
The short term hope of upgrading quickly for "my sake", has fu%$ed over many other pilots. You call this a backstabbing industry. An industry doesn't exist on its own. It is made of and comprises individual people who make choices on their own. Thus, it would be more accurate to say that this industry is made of backstabbing people. We've seen these people on this thread.
Here is the deal: If NO ONE went to GoJet, they couldn't operate and they would have HAD to have offered a reasonable compensation package.... PERIOD. The fact that some scabs went there just fueled the fire and proved to management how little we think we are worth. They are laughing all the way to the bank because of these guys.
Now that 50 seaters are going out of style and TSA is stuck in the AA scope, who gets to fly the 70 seaters? GoJet. Then who can't feed their families? The TSA pilots. Most TSA pilots would rather shove their sacks into a door jam than work for GoJet. But lets say hypothetically, they adopted the mentality of "I've got to feed my family", so they jump ship to GoJet. What has this done? Its moved the bar even lower for everyone else.
And as an extension to this thought: If pilots said to Mesa, "enough is enough, we won't work for you any more." Mesa would be forced to increase the quality over there. Because pilots have proven they will work for shiit, Mesa is the most ridiculed and hated regional there is.
Perhaps this "brotherhood of pilots" is BS. But regarding GoJet, don't forget who actually did say "NO"!
