The United Food & Commercial Workers said its 43,000 members will have a new contract or walk picket lines Sunday.

The union and Stop & Shop are scheduled to resume negotiations Thursday.

The five UFCW locals and Stop & Shop have been bargaining for months without a resolution, despite the expiration of the old contract that covered workers in Connecticut, Rhode Island and Massachusetts.

Brian Petronella, UFCW Local 371 president and an international UFCW vice president, said all five locals have scheduled votes on a new contract for Sunday. Members of Local 371 will meet in Bridgeport.

Westport-based Local 371 represents approximately 5,000 meat cutters and deli workers at Connecticut and some Massachusetts Stop & Shops.

Farmington-based Local 919 represents almost 10,000 workers including clerks, cashiers and Dunkin' Donuts workers within the supermarkets.

The locals said they handed Stop & Shop officials a comprehensive contract last Saturday. The two sides have not met since, as Stop & Shop goes over the proposal, according to Petronella. Negotiaions could run through Saturday.
