I disagree with your post.
Decades ago, Unions were needed to protect workers rights. It was more about the overall working conditions and oppression of the work force. Company stores, unsafe conditions, no paid time off. Things like that.
In those days, our benevolent government did not regulate working conditions or a minimum wage. Thus, the Unions were needed to protect us from shady owners.
For a long time, this has not been true. The unions have become simply a tool for extracting more money from a company and going primarily into the hands the unions versus the workers. Unions routinely demand ridiculous wages for low skilled employment.
Think about the MASSIVE economic damage that the unions have done and are still doing.
Just this week in France, the baggage guys went on strike. It estimated to have caused more than a billion € in damage to the EU economy.
Do these asshole have the right to take money from my pocket because they do not like their job?? I should suffer because they feel they need 25€/hr to put a fucking bag on a trolley?
Think back to the 70's and 80's in the UK. The unions single-handedly destroyed the UK automotive production industry.
Same in the US.
GM, Ford, Chrysler. None of them were able to compete with foriegn car companies because of the unions. What? You need an extra run of cars? Well, we need triple time pay for that. We need at least 80 bucks an hour to stick a fucking screw into a hole.
Because of unions, it is not even possible to keep an excellent new teacher and fire a terrible old teacher simply because she has been there for 15 years. It doesnt matter if she knows how to teach or not.
No, the net impact of unions in this day and age, is negative.
