Amazon workers at JFK8, the company’s Staten Island fulfillment center that voted to unionize earlier this year, held a sit-in, wildcat strike last night after a fire broke out in the warehouse.Seth Goldstein, a lawyer for the Amazon Labor Union, said that the compactor in question had been causing problems and smoking for weeks before Monday, according to employees in the warehouse.Where’s the transparency here?”The JFK8 fulfillment center made headlines earlier this year for becoming the first Amazon location to organize.Goldstein said the warehouse needs to be investigated for safety concerns by the city of New York and by the Occupational Safety and Health Administration.“I’m calling out to New York, to the Department of Labor, to the Fire Department, to make sure workers have safety when they go into work.”"
