Abstract The article presents information on some problems of labor union auditing. Organized labor has traditionally regarded criticism of its financial machinery as an attempt on the part of employer groups to weaken its influence and bargaining power. The unions believe that much of the criticism has not been of a constructive nature and has emanated from those whose economic interests were, prior to the present war emergency and the resultant cooperation between labor and management, opposed to their own. Along with this has gone a hesitancy to engage independent auditors who, because their work is closely connected with business enterprises, have been associated in the thinking of labor union members with employers who may have done everything in their power to discourage or destroy organization among their employees. Many unions that engage independent public accountants require that audits be made monthly. In some cases the audits are made by a board of trustees selected by the union membership at regular elections or by special auditing committees elected each time an audit is required.
