In Frasier v. Model Coverall Service, Inc, 182 Mich App 741, 744; 453 NW2d 301 (1990), the claimant was off work due to a work-related disability when he accepted a non-disability retirement. The Frasier Court, noting that the rules of statutory construction required it to give the phrase "active employment" in 373(1) its ordinary meaning, held that because the claimant was off work due to a work-related injury and was not performing his customary duties at the time he retired, he was not engaged in active employment at that time.
