> The reason for this rule is that it forces management to schedule workers more predictably and compensates workers who invest in obtaining broader qualifications.

No, it's just a scam, and anyone should be able to see that. It's like saying I get 2 days pay if I have to write go in addition to typescript. And 3 days pay if I have to write java.

> There are literally thousands of unions just in the US. I agree that some are dysfunctional, but making a claim like "with some exceptions -- unions today are mostly bad" needs a lot more evidence. My counter-evidence is simple: historically, there's a direct correlation with the strength of unions and the existence of a strong middle class.

Unions had a good reason to exist post industrialization when many people worked in factories under terrible conditions. But today, in the West, that's no longer the case. Today, unions are mostly bad.
