The agenda of the workers (benefits, pay, working conditions, etc.) rather than the agenda of the organizers/leaders. If the workers want social issues as their agenda then that's fine but there should be a broad voting process for that rather than a dictatorial preemptive agenda. This just seems like a few dozen people trying to tell 100k what they should care about.

edit: I don't think I've ever seen environmentalism come up as a desirable goal from proponents when people discussed tech unions. Pay, benefits, working conditions, abusive management and so on but environmentalism????
