A union official says General Motors Corp.'s plan to close its service and parts warehousing and distribution center in Massachusetts will leave about 66 union workers jobless.
Al Lamoureux of the United Auto Workers of America Local 422 said Monday that GM plans to transfer the work to its Philadelphia operation by the end of the year.
The center in Norton, west of Boston, serves GM dealers in New England and parts of New York state.
Lamoureux said Massachusetts workers affected include 57 union members on the payroll, nine on layoffs and about 14 salaried workers.
He said it's not immediately clear if workers will have the option to follow their jobs to the new location.
Union leaders plan to lobby members of Congress to press the federal government to keep the Massachusetts operation open.
