Members of United Auto Workers Local 2069 continued to strike outside Volvo Trucks North America in Dublin on Monday, while inside, the plant sat quiet.

"Everything's going good so far," UAW Local 2069 Vice President Tim Barnes said Monday morning. "We have people out there 24 hours" a day.

More than 2,460 of the plant's 2,900 employees are members of UAW Local 2069, and union officials said all members would be taking their place on the picket line in coming days.

Volvo spokesman Jim McNamara confirmed the plant was not in production Monday, but declined to talk about when -- or how -- production might resume.

The plant produces all Volvo trucks sold in the United States, Canada and Mexico.

UAW Local 2069 first went on strike about midnight Thursday after its bargaining committee failed to reach a tentative contract agreement with Volvo.

Contract negotiations between the two groups first began in early January, and union members voted Jan. 28 to authorize a strike in the event an agreement could not be reached by the time the current contract ended.

In a letter outlining union members' reasons for striking, UAW Local 2069 President Lester Hancock blamed "unreasonable proposals that would erode the wages and benefits that we've fought so many years to achieve and protect" as well as efforts "to dismantle many of the most basic health and safety protections found in our current agreement."

Hancock said Monday that the union is willing to negotiate with Volvo at any time.

"We're just still waiting for the company to contact us," he said.

While the picket line continued in Dublin, two politicians campaigning for the Democratic presidential nomination weighed in with their own thoughts about the strike.

In a news release sent Saturday, U.S. Sen. Barack Obama said, "I stand with the workers who are striking Volvo. The union's demands -- job security, health benefits and safety protections -- are basic guarantees that all workers should expect and that UAW members deserve."

U.S. Sen. Hillary Clinton offered a similar response.

"I fully support the working men and women of United Auto Workers Local 2069 at the Volvo Plant in Dublin in their ongoing efforts to organize and bargain collectively for a safe workplace, skills training, fair wages and meaningful health and pension benefits," she said in a release.
