diversified investment, and had no board representation. When Enron collapsed in 2003, employees lost a majority of their pension savings. For this reason, employees and unions have sought representation because they invest their labor in the firm, and do not want undiversifiable capital risk. Empirical research suggests by 1999 there were at least 35 major employee representation plans with worker directors, though often linked to corporate stock. As well as representation on a corporation's board of directors, or top management, employees have sought binding rights (for instance, over working time, break arrangement, and layoffs) in their organizations through elected work councils. After the National War Labor Board was established by the Woodrow Wilson administration, firms established work councils with some rights throughout the 1920s. Frequently, however, management refused to concede the "right to employ and discharge, the direction of the working forces, and the management of the business" in any way, which from the workforce perspective defeated the object. As the US presidency changed to the Republican party during the 1920s, work "councils" were often instituted by employers that did not have free elections or proceedings, to forestall independent labor unions' right to collective bargaining. For this reason, the National Labor Relations Act of 1935 §158(a)(2) ensured it was an unfair labor practice for an employer "to dominate or interfere with the formation or administration of any labor organization, or contribute financial or other support to it". This was designed to enable free work councils, genuinely independent from management, but not dominated work councils or so called "company unions". For example, a work council law was passed by the US government in Allied-occupied Germany called Control Council Law, No 22. This empowered German workers to organize work councils if elected by democratic methods, with secret ballots, using participation of free labor unions, with basic functions ranging from how to apply collective agreements, regulating health and safety, rules for engagements, dismissals and grievances, proposals for improving work methods, and organizing social and welfare facilities. These rules were subsequently updated and adopted in German law, although American employees themselves did not yet develop a practice of bargaining for work councils, nor did states implement work council rules, even though neither were preempted by the National Labor Relations Act of 1935. In 1992, the National Labor Relations Board in its Electromation, Inc, and EI du Pont de Nemours, decisions confirmed that while management
