Historically, here in the US, things like 40 hour weeks, two-day weekends, overtime pay, safety protections, etc. came about because of union actions and the political climate they created.
English allows your "must be" to be interpreted two common ways.
1. A comment about how in general there should be a way to do that, but not engaging in the topic, ceding all power to the corporations which would be glad to take it, giving none back, and just mildly sneering at anyone foolish enough to join such a basal endeavor as a union.
2. A comment about how we would need to accomplish that goal and that establishing the working process should come before unionizing as it is the proper solution to the problem, ceding all power to the corporations which would be glad to take it until we solved the problem that is effectively created by corporations to be unsolveable.
Collective action works, it solves problems, it gives workers space to live and have basic rights, and we don't have to throw up our hands and say "there must be a better way!"
Laws change every day. There must be a working process for that.
