what can be an underlying reason for an employee Not to accept a salary-hike / promotion. is he a person of low self esteem ?
"a salary-hike / promotion"
Not all promotions are worth the additional time and stress needed to do the job. Many people are realizing family time is worth more than the ability to buy a "new and improved" X-Box or a fancy car.
Money can't buy happiness.
not qualified, not prepared, not ready.... it's their choice....and their reason...
It's kinda like asking god why your not in heaven yet...
pointless....complex....and unknown answer.
