Patrick Cassidy was working as a carpenter when he saw the newspaper notice about job opportunities at Vineyard Wind in the summer of 2019. The country’s first commercial-scale offshore wind farm was being built 15 miles south of Martha’s Vineyard, the island he’d called home since 1995, and he was curious. He enjoyed his work, and he was good at it, but he liked the idea of a more regular paycheck — and maybe even paid time off.
