A potential strike is looming at the Stop & Shop distribution center in Freetown. 

Teamsters Local 25 is accusing the grocery store chain of forcing workers to give up health care benefits to save the warehouse from outsourcing. 

In a statement, Stop & Shop said it's offering wage increases, increased pension contributions and a more competitive health care plan. 

The union says if a settlement isn't reached picket lines will go up outside every Stop & Shop in New England.
