Governor Tom Wolf announced Tuesday that Pennsylvania will fulfill its commitment to raise the minimum wage for commonwealth employees to $15 per hour by January 31. An increase to $12 would directly benefit 765,000 Pennsylvania workers, or more than 13 percent of the employed population. An increase to $15 would directly benefit nearly 1.5 million workers, or 25 percent of Pennsylvania workers. According to a new report from the National Employment Law Project, 21 states raised their minimum wages on Jan. 1.
