Hundreds of warehouse workers for New York City’s B&H Photo Video have voted overwhelmingly to unionize. Wednesday’s 200-to-88 vote to join the United Steelworkers union comes after the warehouse workers organized for more than a year with the support of the group, the Laundry Workers Center. The workers are now demanding a contract that will protect them from what they describe as dangerous working conditions inside B&H’s two Brooklyn warehouses.
