A strike at Navy shipbuilder Bath Iron Works entered a fourth week on Monday with no talks between the company and the union representing 4,300 production workers.

Both the company and Machinists Local S6 met separately with a federal mediator last week, but there has been no resumption of talks.

Shipbuilders went on strike June 22 after overwhelmingly rejecting a three-year contract proposal from the company.

The dispute isn’t over money. The company offered annual 3 percent raises but the union is focused on the hiring of subcontractors, changes in work rules and issues involving seniority.

The company has maintained that it has the right to hire subcontractors but wants to streamline the process to be competitive.
