Industrial unionism is a labour union organizing method through which all workers in the same industry are organized into the same union—regardless of skill or trade—thus giving workers in one industry, or in all industries, more leverage in bargaining and in strike situations.

Industrial unionism contrasts with craft unionism, which organizes workers along lines of their specific trades, i.e., workers using the same kind of tools, or doing the same kind of work with approximately the same level of skill, even if this leads to multiple union locals (with different contracts, and different expiration dates) in the same workplace.
