<prompt> Human: I work for a small start up. When I started I was straight out of college so didnt have much leverage in negotiation. I have now been there for a year. I work with biggermore important clients than my coworker who is 3 years older than me. We have the same job title, however I just found out she makes 10,000 more than me. I am having a yearly review with my boss on Thursday, he wants to discuss my bonus for the past year and my contract for next year. My boss told me I was the best hire of his career however, when I asked for my bonus he asked me to discuss in person with him so we can go over my yearly performance. I am planning to go into the talk with concrete proof of the value I bring the company, but am planning to negotiate my bonus for the past year and my salary as well as equity for next year as well, so I want to be sure I play my cards right. So I have two questions:a. Is asking for a 10,000 raise 16.6 of my total salary too extreme ?b. can I bring up the fact that I know how much my co-worker makes ?  <response>: I wouldnt bring up that you know your coworkers salary. Not to get into the you can talk about it legally versus you shouldnt, it doesnt help your cause because its what your coworker makes. Maybe theyre underpaid too! Your negotiation should be about the value you bring to the table. Look across the market at what your job should be bringing in and go for that number. B just makes A easier to reconcile. To me, its too risky to possibly encounter a bossHR approval that isnt a fan of you knowing your coworkers salary unless of course its public, but at a startup thats not likely.
