Patna: The Patna high court has directed the state govt to grant graduate-trained grade pay (Rs 11,000 per month) to all ‘niyojit’ trained and graduate teachers of middle schools, appointed between 2006 and 2012. The high court directed the additional chief secretary of the education department to complete the exercise of equalising the grade pay of all middle school ‘niyojit’ graduate teachers in Bihar within three months.Since the grade pay of graduate trained middle school ‘niyojit’ teachers was first introduced by the state govt by framing a new service conditions rules on April 3, 2012, many such eligible middle school teachers appointed prior to the date are being paid lesser than their colleagues.A single bench of justice Purnendu Singh while allowing a writ petition of one Rajesh Kumar Pandey delivered this judgment on Monday, a copy of which was uploaded on the HC websites on Tuesday evening.Justice Singh held such difference in salary for the middle school ‘niyojit’ teachers in Bihar as discriminatory and in violation of the fundamental rights guaranteed by the constitution of India.
