The state-controlled district approved a $476 million budget for the upcoming school year.
Although Camden is receiving a $23 million increase in state funding, district officials say rising costs are driving the need to cut back.
At Tuesday night's advisory board public hearing, teachers and residents voiced their frustration.
"More cuts, less services - more workload on my teachers," one speaker said.
"What we're seeing here is not an accident. This was calculated and done by politicians," another resident told the board.
District officials said about 100 staff members have been notified, including 21 teachers who could be reassigned.
