Many years ago they were essential. At that time they did work to improve conditions, the pay of working men and women. Regrettably, a number years later they ended up being controlled by people that didn’t have morals or ethics (many were criminals). No longer did the unions have the best interests of their members at heart. I know this because I had personal experience with one. The union’s priority then as it is now is making the leaders richer. They impede the workings of the city, and inconvenience it’s population.
