I learned this thirty years ago working at U.S. Steel.
Unions are loyal to the unions first and foremost. I worked at a refinery and had to deal with the OCAW. Despite that fact that they get their paychecks from Shell Oil, they are loyal to the union only. Shell who?
Makes sense that the dimrat politicians align themselves with the unions. They are loyal to their party first and foremost, not to this country. Sure they live here, but they are loyal to their party. Same mindset.
