Yes, they are. When an organisation has a sole control of the supply of a good or service, it is a monopoly, and they are invariably bad, because the organisation’s incentive to provide a good service is essentially removed. I see no difference between Microsoft using their stranglehold on the OS business to force PC builders not to use any other OS, and a union using its stranglehold on the supply of a type of labour to force a company not to use any other source of labour. There is nothing magic about labour that means it can’t be monopolised, nor anything that means it must be monopolised to gain a good market position.
Yes, my point is not that these people don’t exist, but that you seem to be assuming they are stupid, and must be protected from themselves. As I said before, if the union offers them an advantage, they will have every opportunity to join it of their own volition, and need not be forced. Speaking of which…
Well, given this paragraph, it’s quite possible that we’re talking past each other. I don’t have a problem with mutually negotiated union exclusivity agreements (assuming neither the union nor the company is under coercion), my problem is when the union becomes so powerful that it attempts to enforce unionisation on an entire industry or location. The example in the OP was a union starting street demonstrations simply because a company had the temerity to come in to town and not give them exclusivity. This, to my mind, is coercion - “give us exclusivity, or we’ll fuck up your play”. They’re trying to squeeze non-union workers out of the entire city of Toronto. You can’t join a union of your own volition if there is no other way to get a job.
I never said organised labour was intrinsically evil, nor do I think such a thing. I completely agree with your last statement, as well as your first. I really don’t think we’re all that far from agreement here; you just think I’m making a broader point about unions than I am.
This I disagree with, and it is handily disproved by the existence of thousands of unions working in and with companies that do not have exclusivity agreements. In a former broadcasting job, I had the choice of joining one of two unions, or none. I chose the latter, since it was a short-term job I had little attachment to. The unions existed quite happily in spite of my non-participation. They negotiated perfectly happily with management, and achieved a lot of their bargaining goals. There was no need for me to be forced to join them.
