By wide margins — and regardless of personal political affiliation — those who design and administer employer health plans are concerned with both Presidential candidates’ health care proposals, saying that Senator John McCain’s proposal to repeal the tax exclusion for employer-provided health coverage and Senator Barack Obama's proposal to compel employers to "pay or play" would have strong negative impacts on American workers, according to the American Benefits Council.Based on a survey of corporate health care executives at large and small organizations, 74 percent said that a repeal of the employee tax exclusion for employer-sponsored health coverage (a McCain proposal) would have a strong negative impact on their workforce; 46 percent said requiring employers to "pay or play" (an Obama proposal) would have a strong negative effect on their workforce; 58 percent said they would like to see the candidates focus more on cost issues, and 74 percent would like more focus on quality.
