As COVID-19 restrictions get lifted and Pennsylvania’s economy tries to get back on track, businesses ranging from fast-food restaurants to manufacturing are clamoring to fill job vacancies — and many are saying they are having trouble luring workers. Labor advocates, though, say businesses are not offering workers enough money in a competitive hiring market still under a pandemic cloud, and there remain obstacles for many lower-wage earners to return to jobs, such as childcare and transportation. In Beaver County, Gregg Troian said he’s encountering a worker shortage firsthand as president of PGT Trucking, a long-haul operator. Troian said he needs 100 drivers, or about 10% of his fleet, but he struggles to find qualified people even though a new driver can make $70,000 a year.
