<prompt> Human: A coworker explained that his significant other who also works for the company but was hired later for the same position as us makes a considerable more than we do. Adding to that a number of new employees have mentioned their rates which have exceeded our own. Its left me feeling betrayed and undervalued as I have more experience and I am considered to be a valuable asset ha!.  <response>: Its never in your interest to say I know what X is making, and its more than me, and I want more!You need to use your new-found knowledge, and make a case for a raise to an amount equal to new hire base more based on your experience. If you make your company a lot of money, talk about that, if you have salary surveys, use them.At the same time, I would update resume if I were you, and look around. Your company clearly doesnt value peoples loyalty, so its time for you to see if you can find a much better gig. Never quit without an offer in hand.
