<prompt> Human: I started working for a very small design firm recently, Im about to negotiate my full time salary with my employer. I looked them up on glassdoor and realized what they offered me is way below my co-workers, is it a good idea to mention that when negotiating? In a non-confrontation way of course.  <response>: I wouldnt necessarily mention Glassdoor directly. Instead go about it by talking about doing research on industry salary standards and discussing with others in the industry leads you to believe you are worth X and from this youre interested in starting a discussion of salary correction options. Im also assuming youve proven yourself at this point before even having the conversation.
