Living and working on Mackinac Island is a dream come true for so many! The first step to living on Mackinac Island for the summer is to get a job or employment on the island. In order to keep business running smoothly Mackinac Island employees over 5,000 summer workers. I have worked a total of 9 summer seasons on Mackinac Island. Jobs and employment are typically from 2-6 months, starting in April/May and ending November 1.
