A report by a Washington think-tank says at least six million American workers will be losing their overtime protections under new Bush administration rules. The Labor Department rules take effect next month. The administration contends no more than 107-thousand high-income workers may lose overtime, while more than one million low-paid workers could pick it up. It dismisses the report as rehashed misinformation. Democrat John Kerry says the changes are a "shameful assault on the paychecks of hardworking Americans." The labor-backed Economic Policy Institute says among those who could lose overtime protection are more than three million workers who will be reclassified as "team leaders" or "executives." Others being reclassified include some chefs, teachers and computer programmers.
