I would say no. It is not possible for someone to accept a job with a salary of Rs. 6,500 while previously drawing Rs. 15,000 or more, except under extreme conditions such as a recession. If he did that, there might be something definitely wrong done by him or the employer. Can you please share more details about it or what you know more about him?
Salary Reduction Concerns
Secondly, if someone is working and drawing Rs. 15,000 or more, and then rejoins after a few days or months of resignation, they can be offered a salary less than Rs. 15,000 but not as low as Rs. 6,500, which is even less than half of his previous earnings. This is not acceptable.
Aksh, is he your colleague, friend, or any personnel (employer)?
