You outa organize a wildcat strike. They should do this at Ground to. I mean what the heck do you have to lose anymore, Fred has taken nearly everything away. And for the Groundies, jeez you guys never had anything to take away, what the H are you waiting for?
Wildcat strikes are by definition, strikes which are taken on a local basis, WITHOUT authority from the main union.
If Express employees were to take a "work action", they would be handed a Warning Letter for the first day they didn't come into work, and their employment would be terminated on the next day if they didn't come in. It would be considered to be a "voluntary resignation" on the employees' part, and they would have NO RECOURSE to get their employment back.
The RLA exists PRECISELY to prevent such a thing if a covered company were to experience a "wildcat strike" (presuming its workforce was already organized and recognized). The RLA provides employers with protections that include the ability of the federal government to ORDER employees who are engaging in strikes that fall outside the "procedures" of the RLA, to be ordered back to work. Companies which are covered under NLRA rules, DON'T have this capability to get the federal government to order employees back to work.
Do some research into the RLA and you'll see why Express has paid so much over the years to keep itself under those rules.
