You missed the point of my union post. Teacher unions in strong union states have power. Florida unions have zero. They cant strike and the school board can implement a contract without the unions approval. Florida unions are not preventing any raise in Florida. The state has attacked a straw man here.
As a general rule, I am not a big supporter of unions in the public sector in particular. They certainly had a place in the private sector during the industrialization of our nation, but today not so much. I have no first-hand experience with unions representing our local law enforcement or firefighters but my interaction with the teachers union over several years in that profession is the basis of my opinion.
