During the battle over comprehensive health care reform in the early 1990s, organized labor was not only unable to put together a winning coalition but also found itself divided and on the defensive as it struggled to prevent any further erosion of the private-sector safety net of the U.S. welfare state. Labor's relative ineffectiveness has deep institutional and political roots and was not merely a consequence of its dwindling membership base. Several key institutions of the private welfare state, notably the Taft-Hartley health and welfare funds and the Employment Retirement Income Security Act (ERISA) preemption, brought the interests of organized labor more closely in line with those of large employers and commercial insurers and aggravated divisions within organized labor and between unions and public interest groups. In addition, several political factors conspired to reinforce labor's tendency to stick to a policy path on health care issues that was predicated on an employer-mandate solution and that had been charted primarily by business and leading Democrats. As a result, organized labor did not emerge from the 1993–1994 struggle with its political base fortified nor with a viable long-term political strategy to achieve universal health care and to shift the political debate over health policy in a more desirable direction.
