Two years into their campaign for a union at UW Health, nurses at the massive Madison-based health care system say the conditions that first prompted their organizing drive have grown worse.

Meanwhile, the hospital administration, which rejected unionization from the start, has embraced more aggressive tactics.

Nurses report that in recent weeks they have been called into meetings with supervisors where they have been scolded about the union campaign. Some also report that they have been threatened with arrest for gathering at shift change in parking lots outside hospital facilities to encourage coworkers to consider supporting unionization.
