MILWAUKEE (AP) — Doctors who wrote medical notes over the weekend excusing protesters at the Wisconsin Capitol from work are getting slammed with angry phone calls and profane e-mails from people telling them they deserve to be thrown in jail, one doctor said Sunday.

The physicians wore lab coats Saturday as they stood on a street corner and offered medical notes to the tens of thousands of protesters who paraded past them. The protesters were rallying against a Republican-backed state bill that would eliminate collective bargaining rights for most state workers.

One of the doctors was Lou Sanner, 59, who practices family medicine at the University of Wisconsin School of Medicine and Public Health. Sanner said he gave out hundreds of notes and that many protesters with whom he spoke seemed to be suffering from stress.

“Some people think it’s a nod-and-a-wink thing but it’s not,” he told The Associated Press on Sunday. “One of the biggest stresses in life is the threat of loss of income, loss of job, loss of health insurance. People have actually been getting ill from this, or they can’t sleep.”
