GARY, Ind. (AP) _ U.S. Steel is laying off another 83 workers at its Gary Works plant for a total of more than 780 jobs eliminated in northwest Indiana this year.

U.S. Steel spokeswoman Sarah Cassella announced the layoffs Thursday. She said the permanent layoffs are part of an “ongoing operational adjustment'' and the workers would be let go at the end of the week.

The (Munster) Times reports (http://bit.ly/1BcWbX5 ) the affected employees worked at the Gary location for less than six months and will receive their last paycheck Saturday. They have no call back rights under the union agreement.

Previously the Pittsburgh-based steelmaker said it would idle its East Chicago tin, which employees nearly 400 people. It also plans to shut its coke-making plant in Gary in May. About 300 people work there.
