Industrial union

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. Advocates of industrial unionism value its contributions to building unity and solidarity, many suggesting the slogans, "an injury to one is an injury to all" and "the longer the picket line, the shorter the strike."

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.

In 1922, Marion Dutton Savage cataloged the disadvantages of craft unionism, as observed by industrial union advocates. These included "distressingly frequent disputes between different craft unions" over jurisdiction; modern industry results in a constant process of phasing out old skills; one trade doing the struck work of another entity is a frequent dilemma; expiration of contracts can be staggered, hindering coordination of strikes. Industrial unionists observe that craft union members are more often required by their contracts to cross the picket lines established by workers in other unions. Likewise, in a strike of (for example) coal miners, unionized railroad workers may be required by their contracts to haul "scab" coal.

Employers find it easier to enforce one bad contract, then use that as a precedent. Employers could also show favoritism to a strategic group of workers. Employers also find it easier to outsource the struck work of a craft union.

A craft union with critical skills may be able to shut down an entire industry. The disadvantage is the harsh feelings of those who may be forced out of work by such an action, yet receive none of the bargained-for benefits.

Savage observed that industrial unionists criticized craft unionism not only for the ineffectiveness in dealing with a single employer, but also against larger corporate conglomerates. A union that challenges such a combination is most effective if its own structure reflects that of the company. Industrial unions likewise do not normally assess prohibitive dues rates common with craft unions, which serve to keep out many workers. Thus, the entire group of workers finds solidarity more elusive.
