With the specter of forced union dues looming over child care providers in Maryland, some providers worry it could hurt those at the very bottom.

"My understanding of the union is that they would automatically take out of our Purchase of Care vouchers as union dues," Sarecia Powers, child care provider in the Cresaptown area, said. "Having to pay what might be an astronomical amount of dues might make providers consider signing on families based upon being paid privately, where the provider gets everything they are being paid. You could have providers turning down Purchase of Care families, and they are the families that need it most. If they can’t find care, it will have a domino effect."

While Maryland Governor Martin O’Malley proclaimed Friday that "no one should be forced to join a union," his is one of 28 states without a Right to Work law where employees can be fired if they refuse to pay union dues.
