Joy Darden-Pipkins has been taking care of her godmother for around 20 years without being paid. “It’s a labor of love,” she said, adding she is grateful to be married to a man who makes enough money to pay the bills and the mortgage. Darden-Pipkins was one of around 30 people who gathered in the parking lot of the Penn Hills office of U.S. Rep. Conor Lamb, D-Mt. Lebanon, on Tuesday. The group gathered to thank Lamb for his support of raising the federal minimum wage to $15 an hour. They also urged him to keep fighting by pressuring colleagues who do not support the change.
