PITTSBURGH (AP) — Workers from Canada protesting a protracted labor dispute at a smelter in Quebec have come to western Pennsylvania to deliver their message to shareholders at Alcoa’s annual meeting in downtown Pittsburgh.

The Pittsburgh Post-Gazette reports that about 150 Aluminerie de Bécancour Inc. smelter workers bused from Quebec gathered Wednesday at the United Steelworkers headquarters. Blowing noisemakers, the workers then marched to the hotel hosting the aluminum giant’s meeting.
