(April 7, 2016, 11:00 AM EDT) -- NEW ORLEANS — The Fifth Circuit U.S. Court of Appeals on March 24 ruled that the National Labor Relations Board did not err when it ruled on a pay dispute filed by two unions against a government contractor after the employer was unclear about its willingness to engage in arbitration; however, it sent the case back to the NLRB for recalculation of severance and vacation pay (Hallmark-Phoenix 3, L.L.C. v. National Labor Relations Board, No. 15-60011, 5th Cir.; 2016 U.S. App. LEXIS 5554)....
