You're advocating sectoral bargaining. Common in the EU. It's probably The Correct Answer™. Though organizing by craft or industry may also achieve what you want. The USA has enterprise bargaining. Sectoral bargaining was proposed. But the corporations (plantation class) nerfed it. The comparative power of Labor, USA vs EU, speaks the merits of sectoral over enterprise bargaining. "Sectoral collective bargaining is an aim of trade unions or labor unions to reach a collective agreement that covers all workers in a sector of the economy. It contrasts to enterprise bargaining where agreements cover individual firms. Generally countries with sectoral collective bargaining have higher rates of union organisation and better coverage of collective agreements than countries with enterprise bargaining." https://en.wikipedia.org/wiki/Sectoral_collective_bargaining https://en.wikipedia.org/wiki/Sectoral_collective_bargaining
