Maryland lawmakers yesterday approved legislation that would effectively require Wal-Mart to boost spending on health care, a direct legislative thrust against a corporate giant that is already on the defensive on many fronts nationwide. "We're looking for responsible businesses to ante up . . . and provide adequate health care," said Sen. Thomas M. Middleton (D-Charles), the Finance Committee chairman, as the Senate approved the measure with a majority wide enough to survive an anticipated veto. A similar bill has cleared the House of Delegates, and legislators expect to reconcile their differences easily. Lawmakers said they did not set out to single out Wal-Mart when they drafted a bill requiring organizations with more than 10,000 employees to spend at least 8 percent of their payroll on health benefits -- or put the money directly into the state's health program for the poor. But as debate raged in the Senate yesterday, it was clear that the giant retailer, which has 15,000 workers in Maryland, was the only company that would be affected. "This is crossing a bridge," said Sen. E.J. Pipkin (Queen Anne's), who joined the Senate's other Republicans in voting against the bill. "Annapolis is telling private business in the private marketplace what to do." Maryland, Gov. Robert L. Ehrlich Jr. (R) is expected to lend his support to the retailer and veto the measure, should the House and Senate reconcile small differences in the bill. [more]
