AMFA did indeed inherit the ibt agreement - Just as the law calls for. As for your misguided take on the contract extensions, sorry to be the one to tell you, its what the MEMBERSHIP wanted. As a TWU parrot its not surprising you can't understand that ... the membership getting what they want.
It is worth pointing out that SWA mechanics make alot more than you, and must be pretty happy with AMFA as "RAID" attempts by both the ibt and your laughable TWU were both sent packing.
As for PFAA, thanks for acknowledging your initial post was a lie - good for you
On Horizon, your TWU was decertified in favor of AMFA. the ibt in turn displaced AMFA, and then after the ibt allowed the outsourcing of all of Horizons heavy maintenance, there was a second AMFA drive which resulted in an election that AMFA lost. I often wonder why they didn't try to go back to the TWU, after all its done for the mechanic profession.
So in closing, after more of your particular brand of dodging and blathering we come back to the obvious conclusion ... your supposed "Facts" weren't
