DETROIT (AP) – A tentative four year contract with striking General Motors gives workers a mix of pay raises, lump sum payments and an $11,000 signing bonus and allows the automaker to proceed with closing its assembly plant in Lordstown.

Also in return, the contracts allows GM to move on factory closures in Warren, Mich., and near Baltimore.

Details were posted today on the union website as factory level union officials met to decide if they’ll approve the deal.

No decision has been made.

Workers went on strike Sept. 16, crippling the company’s U.S. production and costing it an estimated $2 billion.

The Detroit Hamtramck plant which GM wanted to close will stay open and a new electric pickup truck will be built there.

There are retirement incentives and buyouts or workers at the closed plants who didn’t transfer to other GM factories.

The deal also shortens the eight years it takes for new hires to reach full wages and gives temporary workers a full-time job after three years of continuous work. Workers hired after 2007 who are paid a lower wage rate will hit the top wage of $32.32 per hour in four years or less.

It also has a $60,000 early retirement incentive for up to 2,000 eligible workers.
