The national average is 4.3 days lost to sickness, while the average for the region is 4.4 days lost.
According to the Dept. of Education there are currently 2,944 people employed as teachers or teaching assistants in Hartlepool.
Chris Keates, general secretary of the NASUWT, said: “It is dangerous and misrepresentative to make an overly simplistic analysis of these figures as often the number of days lost can be influenced by a small number of teachers who may have serious long-term illnesses.
“While the government and employers fail to take seriously their responsibilities to tackle some of the serious challenges in teaching, such as excessive workload, teachers’ physical and mental health will continue to deteriorate, often with the result good teachers are lost to the profession”
A spokesman for Hartlepool Council said: “Hartlepool borough council’s HR services work closely with those schools and academies that buy back their services to manage sickness absence, so that the education of children in Hartlepool remains unaffected.
“The council assists schools and academies to closely monitor sickness absence and actively manage cases on an individual basis.
“They promote an early intervention approach to enable staff to receive targeted wellbeing support to ensure they’re able to return to work as quick as possible.”
