I used to work for Flex and Personally I never had any problems with management. But I know those that did. I don't know if a union will help or not, but I talked to some friends that still work there and they seem to think that the union drive will fail, like it has in the past, because it is the minority that is making all the noise. I do truly wish Flex becomes more competative and adds more aircarft to the fleet, as oppose just upgrading.
They still have a 2 year contract and are still hiring at a good rate. I hope all my ex partners are doing well, and I'll see you on the road.
