NEW YORK (AP) — Utility workers who have been locked out all month by Consolidated Edison charged Wednesday that the managers and replacement workers who are doing their jobs are not following safety procedures and are potentially endangering the public.

“We are greatly concerned that the replacement management workers and outside contractors are working without the necessary or required permits and certificates and are not working safely,” said Harry Farrell, president of Local 1-2 of the Utility Workers Union of America.
