Delayed Training/Joining letter

My name is Sourav, a resident of Jharkhand and writing this message to seek advice regarding a recruitment process of Airports Authority Of India. AAI published an advertisement(Advt. No.- ER/01/2022) notification on 30/09/2022 for Junior Assistant(Fire Services), Senior Assistant(Accounts) and Senior Assistant(Finance) for Eastern Region for which exams were held on 04/01/2023 and result declared on 14/04/23. I’m one of the selected candidates of Junior Assistant(Fire Services) and awaiting training letters for the last nine months. We are constantly trying to seek reasons for this prolonged delay from AAI but non of their officers reply. Only JA(Fire Services) candidates are awaiting their joining and other two dept. candidates have Joined the organisation. I and all the selected candidates are in deep distress over this behaviour of AAI. On behalf of all the selected candidates, I request you to please guide us if we can approach Honb. High Court and the further chances of it. Kindly guide. Thanks & regards Suman
