Dear All,
Manoj's query is simple. He wants to know whether its legally ok for a HR executive to sign letters. He is not referring to his own authority to sign, rather his experience letter which has been signed by an HR executive.
As far as there is proper authorisation in the company's signatory matrix, an HR exec is also authorised to sign. I think the university is asking because as per them, unless there is something fishy in the exit, a junior person would not usually sign. In which case, I think you need to convince the university that the letter is authentic, and there is no other HR person in the organisation.
