Dear Maheshwari, more inputs are needed for a university covered by the norms of various regulatory bodies such as UGC, AICTE, MCI, etc. Whether it is a State University, Private University, or a Deemed University?
Legal Position on University Staff Employment
That apart, the established legal position is that although education is an industry, a teacher is not a workman. Therefore, you cannot agitate against the issue of the engagement of teaching staff through contractors. If the conditions of their employment, such as salary, leave benefits, etc., are less than the norms fixed by the concerned regulatory authority, you have to make a complaint to such authority only.
