A dozen workers at one of Connecticut’s high profile tech companies, FuelCell Energy, voted Friday to become members of a union. The FuelCell Energy employees work are joining Local 478 of the International Union of Operating Engineers, according to organizers of the unionization drive. The workers voted 8-4 to join Local 478 after having launched their drive to join the union in October 2021. The workers, who will now be represented by the IUOE, are system operators in the company’s Global Monitoring & Control Center. They remotely control fuel cell units in various locations across the country. Joseph Campoli, the organizer for the campaign, said the system operators reached out to Local 478 leaders, after determining their pay was far below the industry standard. “I believe working class people across the country are increasingly frustrated with the wage disparities between themselves and upper management,” Campoli said.
