The International Brotherhood of Teamsters announced that members at Anheuser-Busch have voted to authorize a strike if the brewing company does not meet demands for a new contract. The vote received 99% approval.

Should the labor union and Anheuser-Busch fail to agree on a new contract by the upcoming Leap Day (February 29th), up to 5,000 workers across the company’s 12 breweries in the U.S. could go on strike.
