Food service worker Sheree Allen poses in the Raise Up offices, a branch of the Fight for $15 union, Thursday, Feb. 10, 2022, in Durham, N.C. After decades of decline, U.S. unions have a new reason for hope: younger workers. Sheree Allen was hoping for benefits when she joined the food service company Chartwells last August. Chartwells says it offers health care, paid time off and a 401 (k) plan to its workers, but Allen says she has never been given information about those benefits despite asking her superiors. When she tested positive for COVID in January, she had to stay home without pay. (AP Photo/Chris Seward)
