Cook County's workforce will be shrinking by as much as 8 percent.
Board president Toni Preckwinkle delivered her first budget address Tuesday morning. She plans on balancing the $3.1 billion budget with the layoffs.
Preckwinkle said her goal is to make county government "leaner and meaner" while continuing good services for residents.
Cook County commissioners must approve a budget by February 28th.
Preckwinkle and Sheriff Tom Dart appear to have reached a truce in the battle over budget cuts. The two negotiated over the weekend.
Preckwinkle wanted Dart to cut his budget by 16 percent, or $73 million. Instead, they have agreed to a smaller cut of 12 percent.
Cook County government is trying to close a $487 million deficit.
