Board president Toni Preckwinkle was joined Wednesday by officials who have made that pledge.
By law, the county board must approve a balanced budget by the end of February.
Preckwinkle said some initiatives have already begun, including a compensation review at county clinics and hospitals. There's also a freeze on capital projects so they can be reviewed.
Preckwinkle said she's cutting her own salary by 10 percent. There was no word on whether the other cuts could result in layoffs.
