The mayor's office said in a statement Friday that layoff notices will be delivered the week of Dec. 5. He says the cuts represent 9 percent of the city's about 11,000 employees and will save about $12 million.
On Wednesday, Bing said the city faces a $45 million cash shortfall by the end of its fiscal year in June.
Bing said the positions will be eliminated by Feb. 25. He said additional 2,000 positions have been eliminated since he took office in 2009.
Bing also ordered an immediate hiring freeze for all civil service positions except the Detroit Water and Sewerage Department.
