A strike by 4,800 Canadian Pacific Railway (TSX:CP) is into its second day.
Saskatchewan Energy and Resources Minister Bill Boyd says each day the strike drags on will have a significant impact.
Boyd says agriculture producers need the rail to move crops.
He says a prolonged strike could hurt potash sales dramatically because the rail is needed to export product around the world.
The minister says it's important to get workers back on the job as soon as possible.
