PHENIX CITY, Ala. — As more than 400 workers continue to be locked out of the WestRock paper mill in East Alabama, the company was looking to hire new employees Thursday during a job fair. The work stoppage as the result of a labor dispute between the company and three unions is in its 112th day. WestRock officials won’t say if today’s hiring event is related to the long-running labor dispute, but it didn’t stop hundreds of job seekers from showing up at a Phenix City hotel. While people lined up at the Courtyard by Marriott to apply for a job, some workers were still on the picket line 25 miles to the south in Cottonton. WestRock is looking for production workers to staff the mill that produces coated board, it is heavy-duty paper that is used in product packaging.
