Monday's ruling focuses on 26,000 union-represented workers who are paid with Medicaid funds to provide home care for disabled or elderly customers.
Workers who sued said they shouldn't have to pay fees to a group that takes positions they disagree with.
Neal Bisno, president of SEIU Health Care Pennsylvania, says the state has 20,000 to 30,000 workers who are employed by consumers and paid with Medicaid dollars, but aren't affected because they don't belong to unions.
Bisno says 5,000 others are employed by private agencies, which weren't covered by the ruling.
