<prompt> Human: Lets say you made a good case to your employer that youve been going above and beyond your normal duties in your role 2 positions worth for a while and they agree to review the position and responsibilities to see if the pay is commensurate. If they say theyll give a 5 raise for example but you think 10 or 15 is more fair, is there a professional way to negotiate this without sounding greedy and after already making a case once? Do most people take any raise theyre given? Kind of a hypothetical situation but Id like to know what you think. Also, lets assume this is a high-performing employee. Thank you.  <response>: Generally speaking, I am doing more than my duties isnt a great case for a substantial raise. Thats a good case for that 5 raise - youre a good employee, they want to give you a small reward.Do your research, figure out how much people with similar qualifications and responsibilities are getting paid in your area. Thats the best case for a raise: proving that local companies are willing to pay more than youre making. Its perfectly reasonable to negotiate a raise. You should be prepared for them to say they wont meet that amount, though.If they say they cant meet that amount, I would ask them what it would take to get you there e.g. multiple raises over a period of time, hitting a certain performance goal, stuff like that. You can take that answer and then decide for yourself if its worth finding another job that pays better.
