The unions refused to take job cuts, preferring instead to foist the additional costs off on local government (cities/towns). So we had more employees doing less work. Public services were worse-impacted because the Governor was forced to institute furlough days, rather than simply leaving everything open but with fewer staff members. In the meantime, our court system was forced to cut so deep they had to suspend trials for a month, and they're not even open normal business hours anymore. As a result, the courts are facing constitutional challenges for failure to provide speedy trials.
