Members of the International Brotherhood of Boilermakers, Local 651, began their picket Sunday, ahead of the impending midnight lockout.

The union contract with the company had expired last month, and efforts to reach a new contract have stalled.  Negotiations will continue.

The Newington plant continues to operate with non-union employees.
