Life is simple… why do people insist on making it complicated?

If you don’t think it’s worth to pay them that much, last drawn salary notwithstanding, then don’t hire.

If they feel you cannot pay them what their worth, forgery of payslip notwithstanding, then they won’t take the job.

Employment is just a willing buyer, willing seller relationship.

There are more things to life to occupy your mind, other than such petty things, that will only give you additional stress.
