DENVER - The 10th Circuit U.S. Court of Appeals on July 5 sanctioned Teamsters Local Union No. 523 after finding for the second time that a decision by Interstate Bakeries and the union to place a previously unrepresented employee at the bottom of the seniority roster constituted an unfair labor practice (National Labor Relations Board v. Teamsters Local Union No. 523, Nos. 11-9538 & 11-9542, 10th Cir.; 2012 U.S. App. LEXIS 13671).
