Without Unions, a lot of top people will take advantage of cheap labor. Which means some people will lose out their jobs to those that will work for dirt cheap, and there is a lot of them out there. BUT, I do believe some Unions do cause a high pay, low effort environment, which causes high spending on poor good and services.
Where I work, union fees are taken out of my paycheck automatically which I disagree with, but the option of joining the union is up to the employee. That's where I have a problem with the Union. They claim that they protect you against the higher ups, but the union is the same. Once the Union acquires power, they will also weild it too, sometimes giving the employee no option but to follow the union. I see so many people who do crap work and are lazy, but they are protected by the union. But my job is protected too so I can't complain too much.
Its a very hard question, pro and cons everywhere. I just hope they figure something better out.
