JACKSON, Mississippi－Nissan Motor Co announced on Thursday it is cutting up to 700 contract workers at its Mississippi assembly plant, citing slowing sales for its vans and Titan pickup trucks.

The move follows Nissan's December announcement that it was cutting 1,000 jobs at two Mexican factories. Reports in May indicated the Japanese automaker would cut production by up to 20 percent in North America, blaming low profits.

Thursday's move comes after the arrest in Japan of former chairman Carlos Ghosn, who led a production expansion in Nissan's largest market.

The company has struggled to sell all those vehicles in recent years, turning heavily to incentives and fleet sales to soak up the excess. Spokeswoman Lloryn Love-Carter said the cuts are unrelated to Ghosn and new managers taking over.

Nissan has 6,400 direct employees and contract workers on production lines in Canton, Mississippi, just north of Jackson. The company has long prided itself on a no-layoff pledge for its direct employees in Canton, and Love-Carter said any affected staff would be moved to new jobs. But that doesn't apply to contract workers, who were cut sharply during the recession.

Love-Carter said the company is offering a buyout to workers aged 55 or older and some layoffs over the next 60 days could be averted as workers quit through attrition.

"We are doing all we can to mitigate the impact to the associate workforce," Love-Carter said.

The company will reduce production of NV Cargo and Passenger vans from two shifts to one.

It will reduce production of Frontier and Titan pickups from three shifts to two. Sales of the larger Titan fell 5 percent in 2018 to about 50,000, while sales of the smaller Frontier rose 7 percent to 80,000. The Frontier will also face challenges in coming months, as Ford and Fiat Chrysler's Jeep division introduce new small trucks.

Nissan plans a new-model Frontier to be made in Canton, which has a 450,000-vehicle capacity.

The company also assembles Altima sedans and Murano SUVs in Mississippi.

Love-Carter said production will fall and some jobs will be cut by attrition at Nissan's 1,600-employee engine factory in Decherd, Tennessee, but that Thursday's announcement doesn't affect its 8,400-employee Smyrna, Tennessee, factory.

Mississippi officials have pointed with pride to Nissan, the state's first major automaker.

The company says it has invested $3.4 billion in Canton since it opened in 2003 and the company has received what could be more than $1 billion worth of subsidies and tax breaks over 30 years.

Nissan went through a bruising union election at the Canton plant in 2017, with workers rejecting United Auto Workers representation.

At the time, 3,700 of the workers on the campus were direct Nissan employees. More than 62 percent of those direct Nissan employees voted against the union.
