I have been an Electro/Optic Engineer for 25yrs and I have never heard of an Engineer union.
Seattle Professional Engineering Employees AssociationThough I do have to say that I believe that most of the problems with the 787 are union related, though probably not in the manner that the OP is suggesting. The primary 787 assembly plant was located in South Carolina specifically to get away from the choking costs of unionized labor in the Seattle area. So outside of the first few units delivered, the 787 really doesn't qualify as a "union-made" machine, which is why I think this is hyperventilating and bloviating over nothing.
Most new aircraft go through teething pains similar to what we're seeing out of the 787 news stories. 99% of the time those teething pains in other aircraft, if they make the news at all, would be reported as "[insert aircraft type here] diverted back to [insert airport here] due to mechanical difficulties. No injuries, and the passengers were loaded into another plane with minimal delays", but now that we have an airplane which GORES a leftist's sacred cow (union labor), we have leftists in the news media playing up every little thing with phrases like, "the TROUBLED Dreamliner..."" and the like.
If I still flew commercial aircraft, I'd have no problem or reservations taking a ride on a 787, and I used to do "damage control" engineering at the Boeing Everett plant (where this plane evidently rolled out).
