BATH, Maine (AP) Striking workers at Bath Iron Works have eliminated pickets outside the shipyard as a show of good faith before the start of voting on a three-year contract proposal.

The 4,300 production workers represented by Machinists Local S6 will begin voting Friday either online or by telephone, instead of in person, because of the pandemic. The tally will be announced Sunday.

The strike began on June 22 after shipbuilders overwhelmingly rejected the company’s final offer because of provisions regarding subcontracting, work rules and seniority.

A federal mediator brought both sides together for a tentative agreement that addresses many of the concerns.
