There's a difference between "this offer shows that I'm underpaid in my current position" and "I decided to move on for a variety of reasons." An employee who gives me solid market data, and is a good performer who likes the current position, does me a favor if they let me know I missed the memo on current market. In most companies, it's 2-4% pretty year into infinity, and if the overall market grows faster than that, independent research may be warranted. Meanwhile, of someone gives notice, rather than starts a conversation, I'd be much more wary. If we don't have a good, open relationship already, a quick raise won't fix that.
