The Oklahoma City School Board on Monday night unanimously approved retroactive pay raises for about 4,250 workers, with experienced teachers and principals set to receive the largest increases.

Board members, however, voted down raises totaling nearly $1 million for 202 central office staff and select operations workers, including members of Superintendent Aurora Lora's cabinet.

The approved pay raises will cost the district $2.6 million — 75 percent of which will come from the district's general fund.

A combination of federal, building and child nutrition funds would cover the remaining 25 percent, officials said.
