LITTLE FALLS — Union employees have voted to ratify a proposed contract and end a 19-day strike at central Minnesota’s Polar Tank Trailer LLC.

About 360 workers will soon be back on the job after ratifying the contract proposal Monday.

Business agent Jim Kiser of the International Association of Machinists and Aerospace Workers District 165 says the vote ends the strike. Kiser did not have exact vote totals.

Polar Tank Trailer makes aluminum, stainless steel and carbon-steel tank trailers. The company has a temporary satellite location in Little Falls, with its primary manufacturing facility in Opole.
