"Our teachers are not taxi drivers. They cannot be called when required and then asked to leave. There is no dearth of trained quality teachers for imparting education," Pradhan said.
Asking the state government to refrain from playing with the future of students, he said a permanent arrangement must be made for the betterment of students instead of resorting to "teacher on call" plan.
Taking exception to Pradhan's criticism, state School and Mass Education minister Debi Prasad Mishra said the Union Minister should not compare teachers with taxi drivers.
The state government wants to make the system smooth and ensure that studies in schools are not affected, he said.
