The Chapel Hill-Carrboro and Orange County school systems will utilize their ability to rehire retired teachers in the case of such a shortage.
The threat of shortages prompted the N.C. General Assembly to allow local districts to hire teachers out of retirement, paying their salaries in addition to existing retirement benefits.
The policy states that teachers who return to work must be retired for at least 12 months.
With this clause, teachers would not be induced into early retirement or retire prematurely simply to collect benefits and salary concurrently.
N.C. Superintendent of Public Instruction Mike Ward said some of the legislative conflict was based on the possibility that the system could be abused.
"(The policy was created) to avoid abuses and protect the integrity of the retirement system, which thus far has been stellar," Ward said.
Raymond Cooke, associate superintendent for human resources, said Orange County Schools officials fear the potential threat of a teacher shortage.
"We're all facing a growing teacher shortage, particularly in math, science and special education," he said. "The state universities just aren't producing."
Cooke also said the policy was needed to maintain the high educational standards of Orange County and the state as a whole.
