Republican lawmakers urged the Department of Labor (DOL) to suspend an upcoming rule that would increase the wages of home care workers to $7.25 an hour.

“At a time when approximately 76 million baby boomers are reaching retirement, the federal government has a compelling interest in containing the cost of long term services and supports and expanding the low-cost care options available to this aging demographic,” the lawmakers wrote Tuesday. “We are deeply troubled that this rule runs contradictory to those goals. Therefore, we urge you to suspend the rule.”

Their letter came the same day advocacy groups expressed concern that the new rules to extend federal minimum wage and overtime pay protections to home care workers could be delayed. Currently, states aren't required to pay home care workers the minimum wage because they fall under the Fair Labor Standards Act’s “companionship exemption,” under which they are denied the benefits.

On Wednesday, the administration also issued regulations requiring companies that do business with the federal government to pay their workers at least $10.10 an hour, which would only benefit home care workers who are federal contractors once the regulation takes effect.

Democrats have been pushing legislation that would increase the federal minimum wage from $7.25 an hour to $10.10 because that would lift full-time minimum wage earners out of poverty. But Republicans have blocked their attempts.
