The district has lost $20 million in state funding this year alone.
Gov. Arnold Schwarzenegger and lawmakers agreed earlier this year to allow districts to cut their school years down to as few as 175 days, in an effort to curb state cuts in education funding.
The six-day cut would translate into a 3.5 percent decrease in salary for Oxnard Union employees.
The school board must still vote on a final agreement.
Numerous Ventura County school districts approved furloughs this school year, but Ojai Unified is the only district so far to cut actual school days, eliminating five.
