Pankaj Jain,New Delhi, Jan 29(UNI) Delhi Assembly Speaker Vijender Gupta has written to Lieutenant Governor V K Saxena, raising concerns over alleged gender-based discrimination in the promotion system for teachers under the Directorate of Education (DoE). According to the representation, the DoE continues to maintain separate seniority lists for male and female teachers. This system has resulted in women teachers waiting significantly longer for promotions despite having higher overall experience and larger numbers in the workforce. The department had earlier indicated that the gender-based seniority lists would be merged. However, promotions are still being carried out under the existing system, prompting allegations that women teachers are being placed at a disadvantage.
