Backers of Milwaukee's paid sick leave ordinance plan to show up at the Milwaukee County Courthouse en masse Friday at the first hearing the ordinance will have in front of a judge. Since Milwaukee voters approved the measure, nearly half the county's suburbs -- including Greenfield, Brown Deer, Oak Creek, and Racine -- are taking steps to institute anti-sick leave measures. Milwaukee 9to5 has sent out an e-mail asking supporters to show up at the courthouse to Room 413 by 10 a.m. today.
