The Juneau County Board approved hiring four open positions Tuesday morning.  Two Nutrition Site Managers in the Aging Department will be open.  Director of Aging, Heidi Randall, said the long-time Mauston Site Manager is retiring and that position will probably be filled with a manager from one of the other elderly nutrition sites in the county.  The board also approved a clerk in the Clerk of Courts and a secretary II in the UW-Extension Office.  The secretary would assist the UW-Extension Agriculture and 4-H Youth Agents.
