MURPHY, Circuit Judge. The Fair Labor Standards Act (FLSA), 29 U.S.C. § 207(a)(1), requires employers to pay overtime to employees who work more than 40 hours per week. In this case, we consider the kind of evidence employees must present to create a jury question over whether they worked overtime.

After the parties’ relationship soured, Viet sued Le and Copier Victor alleging that they wrongly failed to pay him overtime.
