In Zanskas v National Staff Management, Inc., 2003 ACO #224, the Michigan Workers' Compensation Appellate Commission recently held that the Supreme Court's analysis of compensable aggravation in Rakestraw applies not only to alleged occupational aggravations of preexisting non-occupational conditions, but also to claims of work-related aggravations of a preexisting work-related condition. Zanskas, id, at 8.
