BOSTON - Two engineers' hourly wages included their per diem expense reimbursement for the purposes of calculating overtime because their per diem pay each week was based on the number of hours they worked, the First Circuit U.S. Court of Appeals ruled April 18 (Eric Newman, et al. v. Advanced Technology Innovation Corp., No. 13-1132, 1st Cir.; 2014 U.S. App. LEXIS 7363).
