Air India has asked its former employees to avoid making negative public comments about the state-owned airline or risk losing their some post-retirement benefits.

“It has been noticed in the recent past that few retired personnel of Air India are tarnishing the image of the company by posting negative remarks about the company on social networking sites like Twitter, Facebook and WhatsApp and also electronic and print media,” Aruna Gopalakrishnan, executive director, said in a 21 June letter to the retired staff and senior Air India management.
