From the abstract:
The passage of Right to Work (RTW) legislation in Michigan was a surprise to many, given its relatively high unionization rate. Previous studies that examine state RTW status and the process of passing RTW legislation are not a good fit for the events in Michigan. Instead, single-party Republican control of state government and a wealthy donor who prioritized RTW combined to introduce legislation, pass it, and sign it into law in a one-week period. Contextual factors helped create an opportunity for this campaign to succeed. The Michigan experience raises questions about long-term strategies for labor in similar environments in the era of big-money donors.
