Performance Transportation Services Inc.'s president said Friday that the car hauler and its related companies were ceasing operations, five days after 1,250 Teamster-member employees went on strike.

The strike included about a dozen employees of Hadley Auto Transport in South Salt Lake. Performance Transportation is Hadley's parent company.

PTS, based in Allen Park, Mich., is North America's second-largest hauler of new vehicles and was operating under Chapter 11 bankruptcy protection.

In a letter to PTS employees, company president and CEO Jeff Cornish said the bankruptcy court on June 4 authorized a 15 percent wage cut for Teamsters-represented employees for two months. "The Teamsters concluded that it was not in their interest to accept our offer," Cornish wrote.
