As the sluggish economy stubbornly hangs on and revenues keep declining, the Bulloch County school system has some tough choices to make to close a nearly $4 million spending gap. The four big cost-cutting ideas presented last week by Charles Wilson, the assistant superintendent of business and finance, to the school board are: Implementing five furlough days for next school year, and the years to come, for all staff. The average employee would take a 2.5-percent pay cut with those furlough days, and the district would save $1.7 million.
