“This represents the death knell to public sector unions...”
I wish you were correct, but the ruling does NOT. The ruling only applies to “home healthcare workers” with even more conditions. This is a very narrow ruling.
Most SCOTUS rulings are narrow, but they establish a precedent that later applies more broadly. The broader implication here is good for right to work laws, it’s good for those who are trying to roll back the power of public employee unions, and it’s good for freedom and liberty. Small steps are sometimes good things.
