Among the thousands of government workers who demonstrated against Wisconsin Gov. Scott Walker over collective bargaining rights were men and women wearing white lab coats and carrying clipboards. Some had stethoscopes around their necks. According to the Wisconsin Republican Party, they were doctors who wrote excuses for the protesters to explain their absence from work. "Phony sick notes passed out to excuse striking union members," the GOP charged in a news release. It's clear that doctors outside the Capitol were distributing notes that public employees attending demonstrations could use in an attempt to explain their absence from work. None of the public employees, however, have gone on strike.
