I'll never forget the union at a convention center that forced vendors to pay them to move anything from their own car they couldn't carry. Nothing but extortionist bullies squeezing every cent of protection money they could out of the people there who actually make things and add value to the world. In contrast, these union employees were nothing but parasites. They did nothing the vendors couldn't do themselves, who WANTED to do it themselves and were fully capable of with their own dollies and carts but weren't allowed to for no other reason than greed. They could have just stayed out of the way and still gotten (over) paid by the convention center but that wasn't good enough. Most people including me justifiably hated those selfish monsters. Name and shame, this was at the Baltimore Convention Center.
And you hear about this all the time in other workplaces. Not allowed to move a monitor to the next desk over because the union guy has to be the one to do it. Not allowed to move a piece of equipment out of the way until the union guy finishes his lunch break and does it.
Unions can be good but unions like this are so bad for everyone around them that it cancels out any good.
