The County Commission on Wednesday denied a request by the county schools to keep lower-paid school workers on the same state pension plan.
Only Commissioners Warren Mackey and Greg Beck supported the school request.
County employees and county school teachers have moved to a hybrid plan that is less costly for government. It applies only to newly hired employees.
Christie Jordan, county school finance director, said there would be minimal savings due to the large turnover among the lower-paid employees. She said there would be extra expense for hiring and training.
She said it would be another impediment to finding workers for the positions that are on duty 201 days a year.
Commissioner Tim Boyd said, "I cannot justify giving benefits that I don't think are sustainable in the long run."
He said in the private sector "part-time" employees would not get such benefits.
