Friday, December 26 is the first of Louisville Metro Government's four furlough days ordered by Mayor Jerry Abramson to help close a $20 million budget shortfall.Spokesperson Kerri Richardson says that means so-called non-essential services and offices will be shut down."Things like getting a permit for a building.....if you want to drop off junk, that wouldn't be available, for example. Those types of services will be closed," Richardson said.The furloughs don't affect any police or fire personnel.It's estimated the four unpaid furlough days will save the city just under $3 million.The other furlough days are January 2, April 3 and May 1st.
