District 4, Communications Workers of America (CWA), AFL-CIO v. NLRB, No. 21-1188 (D.C. Cir. 2023)
Annotate this Case
Before the parties arrived at the 2016 labor agreement at issue, the Company’s benefit plan offered bargaining-unit employees a tax-advantaged defined contribution plan under Internal Revenue Code Section 401(k)—a “401(k)” for short. When the Company upgraded its retirement-benefit offering in 2018, the Union brought the unfair labor practice charge at issue here. The Union claimed that the Company unilaterally modified the parties’ collective bargaining agreement by “implementing a 401(k) contribution matching structure other than that specifically negotiated and memorialized in the CBA [Collective Bargaining Agreement].” The parties dispute which of the two documents—with different 401(k) terms—reflects their final and binding agreement
The Company asserted, and the National Labor Relations Board (the Board) determined that the binding agreement is September 16, 2016, Memorandum of Agreement, as a hand signed by Company and Union bargaining representatives. The Union asserts that a different contract document, as typed up and circulated to the parties almost a year later, is the one that binds.
The DC Circuit denied the Union’s petition for review. The court held that here the parol evidence of the parties' bargaining history allowed the Board to identify the Memorandum of Agreement as the final product of the parties’ negotiations and to conclude that the 401(k) term in the 2017 revised version of the Collective Bargaining Agreement contained an unenforceable unilateral mistake.
