Precisely... I would say never accept a counter offer. If you decided to leave there must be other things that bother you besides money. Those reasons aren't going to change. So if you accept more money you would be happier for about 6 months and then reality will settle in... and would still be unhappy and planning to leave anyway. Even if you are happy with your current job and the only reason to leave is to have a pay increase, when you receive a counter offer with more money you shouldn't stay either. Because a raise by means of counter offer, means that salary at your current employer aren't fair and are based just on negotiation skills alone.
