sports, I worked many years as part of a union, and unions are not always the answer. If you can find a good deal with a good company, with good benefits, and no union involvement, you are way better off.
Where I work now, is non-union, and our people get way better benefits and bonuses. Don't get me wrong, unions had their place at one time. But the shit I seen, would make you sick. Guys on construction crews shooting up heroin, but taking 6 tries to get him fired, after much help offered to the individual. I could sit here all day and give you examples.
Just too many people abusing the system. if the abusing didn't happen, unions would work just fine.
