Nearly every major union I've seen supports seniority-based promotions. I imagine that this is not popular with many employees, and so it cannot be a part of their initial pitch — as you said, not the only approach unions use. If established unions support seniority-based promotions but nascent ones don't publicly support them, it would follow that they must develop into supporting seniority-based promotions. This is…
