Stop & Shop workers across the Northeast could go on strike if a contract dispute isn't settled by Friday.

Union leaders have accused the company of threatening to strip workers of their union health care at the grocery chain's Massachusetts distribution center.

Stop & Shop claims the new contract offers the same health care plan as management, with 25% wage increases over a five-year period, while maintaining pension benefits.

In a letter to the company, the treasurers of Rhode Island, Massachusetts and Connecticut expressed concern over a potential strike.

"A strike impacting over 900 Teamsters, as well as potentially 30,000 UFCW members throughout New England, would have far-reaching operational and economic consequences," the letter says.

Stop & Shop has more than 80 locations across Connecticut, and if an agreement isn't reached by Friday, the company says it will shut down the Massachusetts distribution center.

Connecticut shoppers will likely feel the effects of the strike immediately.
