Accident Fund will sponsor Sparrow Hospital's Occupational Health Services Program.
It pledged a five year, $50,000 donation Friday.
Sparrow says corporate donations are becoming increasingly important.
"With philanthropy, we are able to extend services, continue to improve services, make sure that we have the most state-of-the-art educational programs for our caregivers," said Stella Cash of Sparrow Hospital.
The occupational health services unit treats 18,000 patients a year, both treating and preventing on-the-job injuries.
