<prompt> Human: For context, I started working at a company full time starting from September of last year, while still finishing up my bachelors by going to class at night. My initial position was basically an admin assistantmarketing role at 14hr. After about 5 months, the current sales coordinator left for another job and I got handed all her duties, without a pay raise or title change even though I had all of her previous responsibilities. Fast forward to a couple of weeks ago, and I finally received my bachelors degree after finishing up my summer class. I had talks with my boss beforehand on my future with the company, and I was promoted into more of a analyst role, and was shifted away from the sales coordinator role. Seeing as how I still hadnt gotten a raise yet even as my job tasks had changed completely and I had obtained a bachelors degree, I talked to my boss about a raise. He told me he would evaluate it and a couple of days later, he called me into his office and offered me 19hr.I was disappointed in this offer, as I had been expecting more money. However, I was prepared in case I was presented with a low ball offer, and had researched the market value of this role on sites like Payscale and Glassdoor, and had also developed a list of reasons why he should offer me more money. He said he would think about it and 3 days later, he called me back into his office. He ended up raising his offer to 25hr, and actually apologizing for lowballing me saying he had done more research and realized his previous offer was out of the market TLDR; Boss lowballed me with 19hr. I asked for more because I knew my market value. He came back and offered me substantially more. Never be afraid to ask for a raise and always negotiate!!!  <response>: Knowing your market value by using research tools is the best thing you can do to negotiate salary. I was hired on at below market and have negotiated my salary up 50 over 4 years from where I started. I had good luck without giving a specific number. Something along the lines of, Youve been giving me 45 review ratings, yet Im paid int he 20 of the area for my position. Id like to see that get up to a more appropriate level. Both times they came with a number bigger than I wouldve offered.
