ELKINS — Teamsters Local 175, the union group representing approximately 500 employees of the AHF Products hardwood plant in Beverly, is urging employees to vote against the upcoming contract renewal on Sunday.

Teamsters officials also announced they will be filing unfair labor practice charges against AHF with the National Labor Relations Board, said Ken Hall, president of the local chapter and general secretary-treasurer for the International Brotherhood of Teamsters.

AHF, a subsidiary of American Industrial Partners, has a current contract with employees that expires today. In an attempt to negotiate a new three-year contract, the Teamsters and the negotiations committee, which includes several Beverly plant employees, said they met resistance when trying to meet with AHF representatives earlier this year.
