It's possible that changing unions can help. How? The NW flight attendants changed unions and eventually voted to accept an agreement almost a year after NW imposed its terms on them. There's hope. Fire the worthless union and replace it. Then that new union can negotiate a better agreement than the term sheets. The worst thing would be to allow the worthless union to sell you an agreement, as then you would likely be stuck with it for six years.How is everyone going to feel getting the term sheets locked in for six years?
Changing unions will not help for at least six years.
