The NLRB continues to enact pro union and worker policy; that is the lever to apply maximum force with until representative turnover in Congress can occur.
I repeat myself for emphasis: workers must organize, and failing that, quit to starve the business or industry of labor (depending on their means, location, other potential employment opportunities, etc). Otherwise the beatings will continue as long as the workers keep showing up (as this very piece the post is referencing describes). I see no other options, having worked back from first principles and systems analysis. If the economy or its subcomponents must be pushed towards failure, that is reasonable. Just as in tech workplaces where dysfunctional business systems continue to function due to unseen (sometimes Herculean) effort, if you allow the dysfunction to occur, no change will be made. You either let the system fail, or you push it to failure.

That number rose from 650 districts in 2020 to 876 districts, across 26 states, in 2023. While smaller, rural districts have been more likely to favor the schedule, larger districts are now shortening their school weeks in an effort to recruit and retain teachers. It's a selling point in an era when schools are facing a national teacher shortage.")

TLDR There is no labor shortage. There is a shortage of labor willing to take the abuse they historically have.
