I wrote resignation, but finally they forced me to write / confess that that letter was written by me,since my original certificate s of degree were with them,,after that they scolded me,insulted me,asked me to slap myself and rub my nose ten times on ground as a punishment ,insult,that was really painful to heart.they avaded 2 months salary.thrown me out of job in a bad time where there are no vacancies. I thaout teaching is a noble profession,but managements are treating teachers like slaves.please suggest what ipc will do in favour of me.if some one else in my position ,he would have committed suicide.to get back my certificate s,I sacrificed my self respect and one year salary.
