When it comes to salaries, promotions, and job offers-business is a game. Except in extreme situations, it's not possible for something to be ethical or unethical. You don't owe your company anything that you didn't explicitly promise. Similarly, they don't owe you anything. If you're bored, underpaid, unhappy, or have a better offer-move on. No need to be so serious about it.
