Unlike other public employees affected by former Republican Gov. Scott Walker’s Act 10, which banned collective bargaining except for cost-of-living pay increases, UW Hospital workers are not state or municipal employees. When the hospital became a public authority separate from the university in 1996, it acquired its own special status. How Act 10 and other laws apply to that status accounts for most of the legal arguments over whether UW Health, one of the largest employers in Dane County, can recognize the union for collective bargaining.
