(CNN) – More than two dozen of the nation's largest labor unions, a coalition that has previously been among the president's most solid bases of support, are taking out full page newspaper ads Wednesday to register their disapproval with the health care reform bill that has formally cleared the Senate Finance Committee.
Only hours after President Obama hailed the committee's passage of the measure as a "critical milestone," the union groups - which include the AFL-CIO and AFSCME - condemn the plan for lacking a public option and imposing stiff penalties on Americans who choose not get health insurance.
The unions also say employers should be required to pay a higher share of health insurance costs and that health care should not be financed by taxes on the most comprehensive health care policies known as "Cadillac plans."
"Unless the bill that goes to the floor of the U.S. Senate makes substantial progress to address the concerns of working men and women, we will oppose it," the ad states.
The ads are running in the Washington Post along with other D.C.-based papers.
