WestRock Co., a Richmond, Virginia-based packaging company, is closing its Wheatley Heights plant and laying off 152 employees, according to a WARN notice filed with the state.

The company said in the filing that the layoffs would take place by the end of October.

WestRock will ship work to an existing company facility in nearby Deer Park, Donna Owens Cox, chief communications officer at WestRock, said Wednesday. That facility employs 110 people, she said.

She added that the laid off employees could apply for positions in Deer Park and elsewhere at the company.

United Steelworkers Local 381 and International Brotherhood of Teamsters Local 813 represent workers at the Wheatley Heights facility, according to the WARN notice.

Neither union would comment.
