Students and City Councilors Stand With Harvard DoubleTree Protestors Employees at the Harvard-owned DoubleTree Suites have picketed, protested, and demanded fair process for the past year and a half. This means that they would like to consider unionizing without losing their jobs. Hilton Hotels manages the property, and has refused to listen to workers’ petitions, employees say. DoubleTree employees have called on Harvard to intercede. The university essentially replied ‘thanks but no thanks’ in a letter last May, despite the fact that all hotel workers who have chosen to join a union in Boston or Cambridge since 1999 have used a similar process.
