From the Wikipedia article:
I read about this elsewhere as well.....that EFCA would set up a regime by which either the employers or the union could ask for federal mediation, and the mediators could impose a *binding* agreement if the two parties are unable to reach an agreement on their own. If EFCA really does that, then that seems like it could potentially be a much bigger deal than the shift away from the secret ballot for unionization. That would be an awful lot of power being invested in the feds.
