UNDATED (WTVB) -Teachers are in demand again. The government says this past summer was the best hiring season for teachers in six years. School districts across the country added 79-thousand jobs between July and September. That reverses a concerning trend. During the past four years, enrollment in public schools grew by an estimated 377-thousand students. Schools should have hired about 62-thousand teachers and other workers to keep up, but instead they cut more than 315-thousand jobs.
