Unions worked in the pre-globalized world.
Once companies can just outsource anything from manufacturing to services the only categories that can really unionize with success are those that can de facto block everything at once (port workers are an example).
Unions still work? They exist and do real work for their members. They can also coordinate and cooperate which is, I think, how some unions managed to put pressure on Israel. Was it maybe Italian dock workers?
That globalism has made unions not-work is just Capitalist Inevitabilism. Yeah okay I’ll give up when the billionaires have fully autonomous robot brigades. But not over globalism.
and not even those; when the ATCs - similar position to port workers - went on strike, Reagan fired them all
the US gov has for almost all of its history been anti-unions
