Nov 25 (Reuters) - Unifor said on Monday its members at

Canadian National Railway ( CNI ) have authorized a strike

action at the railroad if the parties fail to reach an agreement

by Jan. 1.

Unifor, which represents more than 3,600 members at the

railroad's Council 4000 and Local 100 committees, said members

voted "overwhelmingly" in favor of the strike action.

CN Rail did not immediately respond to a Reuters request for

comment.

Unifor, which represents CN Rail's car technicians and heavy

duty mechanics among other workers, said negotiations with the

railroad will resume from Nov. 30 to Dec. 8 in Montreal.

The union had initiated negotiations with CN Rail in

September, with bargaining priorities that included higher

wages, addressing concerns about the pension plan and job

security for its members.
