Is it mandatory for a government agency to issue Experience certificate to its employees specifying the work done and category of work, if Iam applying for UPSC. If so, is there a time frame for issuing the certificate. There has been an inordinate delay in issuing the experience certificate i.e., it has not been issued yet due to which the application period has been lapsed and this stint has been continuing for the previous two applications too, wherein I have requested the experience certificate for than a month before the last date, due which i was unable to apply for any other post. Is there any legal modality I can use for this situation.?
