Dismantle it...
Force it into bankruptcy, dismantle the unions, cut the pensions and medical benefits, change the hours of service provisions and get real with the organization. No fancy 'buy outs'. There is so much dead wood in this outfit, its pathetic, it makes it impossible to operate efficently.
Quit the bickering if it was AC/CDN or any other component. The game has changed. Best to start working together.
Been there, done that.
