In an action against employer for an alleged violation of FLSA in denying compensation for the time which employee spent at medical appointments, summary judgment for employee is affirmed over claims that: 1) employee failed to present sufficient evidence showing attendance of medical appointment at the direction of the company; 2) a waiver of FLSA rights when employee chose to take an unpaid excused absence for the time missed; and 3) even if FLSA rights are non-waivable, employee is not entitled to the full amount of time away from work.
