This is all very interesting stuff. Exciting time to be alive.
A lot of the tyranny that we have seen through our history on this planet has started off with somebody deciding that they know what's good for others better than they do for themselves, so they'd just be better off if you could make their decisions for them. The truth is that you don't get to make those decisions for other people, regardless of how important their compliance is to your own plans.
It sounds like you have zero experience with unions.
You can't stop people from seeking employment. Period. You don't have that right. It's crazy to me that I even have to type these words out. You think you have power by withdrawing your labor but you don't for the exact reason you're arbitrarily trying to forbid -- someone else will take your job because there are far more people willing to do it than there is demand for.
The onus is on you to find a job where your skills meet the price you're willing to take. Others will do the same, even if it means sidestepping you yelling across the street from the warehouse.
