GM says hundreds of temporary workers will get full-time jobs by March 31

More than 1,350 temporary workers at 14 General Motors facilities in the U.S. will get full-time positions before the end of March, the company says. 

The workers will start at $21 to $24 per hour depending on their seniority. They'll get improved health care benefits, company 401(k) contributions and annual profit-sharing checks. 

Eventually they'll reach the top wage for a full-time production worker of $32.32 per hour. 

The manufacturing plants and other sites are in Michigan, Indiana, New York, Tennessee, Missouri, Kansas and Kentucky.
