This is a scary thing to me…….the automaker suing a union over a blockade of a plant.

General Motors of Canada is seeking C$1.5 million ($1.47 million ) in damages from the Canadian Auto Workers union and is seeking an injunction against the union’s blockade of the company’s Oshawa, Ontario, headquarters, court documents showed.

The union’s blockade has prevented anyone from entering the headquarters for eight days now. Union members set up the blockade after GM announced last week it would close its Oshawa truck plant in September 2009, with up to 2,600 workers losing their jobs.

The company and the union signed a new contract agreement just two weeks before the GM announcement. In the contract, GM said it would keep the plant open until 2011.

But the company said a sudden and drastic shift by U.S. consumers away from gas-thirsty trucks and sport utility vehicles is forcing it to close the truck plant, along with two others in United States and one in Mexico.
