Well unlike you I have no illusions regarding breaking of contracts and US and their legal team to be successful in that endeavor.
I did some homework on this and I found the both the UAW and the United Food & Commercial Workers both on multiple occassions presented options that allowed them to secure work that was in jeopardy. In fact UF&CW actually went so far as to take over unprofitable A&P stores in the Philadelphia market, several of which are still open and owned by their employees.
So my suggestion was not only supported by prior documented successes, but a genuine attempt to offer a possible middle ground. While it apears that IAM is on solid legal footing, you have to ask yourself if you want to risk it all in court. Any decent lawyer will tell you that open court is somewhat of a crap shoot.
You might also note that I am not a huge fan of outsourcing when there are legitimate safety and compliance concerns that doing the s-checks entail.
Additionally I stated that I didn't know all of the ins and outs of this issue and that is why I posed the questions I did. For the record I do have a life, and a great deal of it is spent on your employers aircraft. So PARDON ME MR. HAPPY, I'll post what I want where I want. Airline safety effects me directly as it is my assets in the seat and I would PREFER that the folks who fix them now, fix them tomorrow. CLEAR ENOUGH BOY GENUIS?
