I actually do see a connection to unions here - if you're not genuinely willing to walk away from a bad deal, you're not actually negotiating. Businesses know this and it sometimes results in temporary outages, such as a TV channel or the Amazon dispute with publishers. In America we hardly have unions any more, and our media reports on strikes (e.g. a railroad strike in France) with derision and as a sign of a failed system. But I see it as a sign of tough negotiations between parties who both have something to lose. Ideally, each industry would have about as many unions as it has employers, and there would be more than one of each.
I actually don't like the idea of being a faceless member of a collective, or causing a great divide between management and workers. But right now we have a situation where one side is organized and using its leverage to drive a tough bargain (with companies growing ever-larger, and more profitable), and the other is just lying down.
