And the overarching problem of it all is you can't just do what you want to get a union. Spreading the word that we're all calling in sick tomorrow won't get you a union contract. Any efforts to create a union from such measures wouldn't be recognized by whatever regulatory body that monitors these things. Legitimate efforts just be made. Get 50% nationwide of a craft to sign union cards to force a vote. And remember if a vote is passed and a national union for FedEx couriers is created FedEx will immediately take all benefits off the table and they will have to be negotiated in a contract. And FedEx will make sure every courier knows that before casting their vote. And a lot more. I'm not saying FedEx doesn't deserve a union. They often act in bad faith. But getting a union and then getting what you want from having a union is often a lot different from expectations.You seem to miss @floridays point. His contention (I agree) is you have to find the underbelly, the vulnerable point to attack, if you expect any chance of success.
You don’t ask hub workers to take the body blows for you, but they are the essential first strike to force FedEx to negotiate.
Hub employees would have to know that couriers and other hourlies have their backs. This is the Achilles heel of this plan.
