Union members at Alcoa in Massena will rally Wednesday afternoon as contract negotiations go down to the wire.

Members of the United Steelworkers Local 450-A and Local 420-A, which represent hourly workers at Alcoa's Massena operations are rallying to show their support for a new contract.

Local 450-A President David LaClair Jr. says the rally will begin at 2 p.m. at the entrance to Alcoa's number 1 gatehouse.

The existing contract between the union and the aluminum giant expires Thursday.
