The use of temporary workers continues to be one of the top discussion points, as the national union leadership and GM officials negotiate.

Indiana has about $900 million invested in the aerospace industry and experts believe that number can grow.

GM Fort Wayne Assembly union workers say they are prepared to strike for as long as it takes to get a new contract. Meanwhile, employees at companies relying on the GM plant face their own challenges.

Metal forming company Brinco says it plans to invest $38.5 million in manufacturing equipment and $13.5 million in real estate.

The facility produces off-highway gears to help power equipment including field sprayers for crops and aerial lifts.

The move comes after failing to agree to a new contract with General Motors over wages, health care and profit-sharing. Nearly 50,000 workers will be affected when production halts.

Grand Rapids, Michigan-based Mill Steel cited a decline in demand for its flat-rolled carbon steel products for the closure.

The move announced Tuesday means that GM will be the focus of bargaining, and any deal with the company will set the pattern for Ford and Fiat Chrysler.

Indiana continues to show success in areas including global reach and tax climate where other states are struggling.

U.S. Steel announced Friday the company will idle its East Chicago Tin mill where an estimated 150 workers could face layoffs.
