Layoffs are coming at the Felman Production LLC plant in Mason County.
The company announced in a news release they will be temporarily idling one of three electric arc furnaces at its ferroalloys plant in New Haven at the end of the month and begin laying off union workers June 3.
The company stated that it had eliminated several management and contract positions already.
The company blames declining silicomanganese prices and increasing manufacturing costs for the cuts. The furnace will remain shut down until market conditions improve, said Felman.
The plant employs more than 200 members of the United Steelworkers. The company and the union agreed on a new 42-month contract in January.
The number of employees expected to be laid off was not released by the company.
