TS should understand what he had achieved will be envied by many in the private sector. Many will not reach a managerial post with an 8K salary even with 9, 10 years of experience. There are many with the same number of experiences but only half the pay with an entry-level position. Why? Because promotion opportunities in the private sector are unlike the rumoured length-based criteria of civil service where one can get at least one promotion if the person stayed long enough.

Also, it is unfair to compare with the finance sector. They are known for paying well but also first to bite the bullet in a crisis.

If he is really unhappy about his current job, he will not hesitate to tender and go to a new post or job and not posting in the forum asking about whether he is shortchanged.
