General Motors has said it planned to cut 50 jobs at a suburban Detroit lithium-ion battery assembly plant announcing last month it would end production of its plug-in hybrid Chevrolet Volt in 2019.

In a filing with the state of Michigan, cited by Reuters, GM disclosed it would cut 37 hourly jobs and 13 salaried jobs in February at its Brownstown Battery plant. GM said on its website the plant had 116 employees.

The plant also assembles lithium-ion batteries for other vehicles that GM is ending production including a hybrid electric Buick LaCrosse.

The job reductions at the Brownstown plant are in addition to cuts GM announced last month. The Detroit automaker said it would end production at five plants in North America, including four in the US, and eliminate up to 15,000 jobs. GM is cutting production of six cars: the Volt, LaCrosse, Chevrolet Impala, Chevrolet Cruze, Cadillac CT6 and Cadillac XTS.

GM said last week it would offer jobs at other assembly plants to 2,800 active hourly workers who work at the plants ending production in Michigan, Ohio and Maryland.

In a separate notice posted on Tuesday, and cited by Reuters, GM said it would lay off nearly 700 people in February at its Detroit-Hamtramck plant that is scheduled to halt production next year. The plant will end production of the Buick LaCrosse and Chevrolet Volt by 1 March and two other cars by June.

GM is cutting 15% of its 54,000 North American salaried workforce and planned to lay off thousands of white collar workers in January after some workers agreed to incentives to depart voluntarily.
