In late 2021 employees became aware that new hires at the collision center were being paid a higher hourly rate than existing workers, according to the decision.
Several workers complained, including a technician who contacted a Tesla vice president and had his complaint forwarded to the company’s head of human resources, according to the ruling.
Supervisors at the service center held a meeting where they instructed the facility’s 25 employees not to discuss their pay and other working conditions and not to file complaints with higher level managers, Rosas said. Weeks later, the technician who had complained was fired, according to the decision.
The technician filed a complaint against Tesla with the NLRB last year, and Tuesday’s ruling came after Rosas held a hearing in February.
