<prompt> Human: I just started a new job this week at a dream company of mine company A. Their offer was way below what I expected and I was only able to negotiate them up from 65k to 68k. I was quite surprised and a little upset with how low the salary offer was but I took it because I was unemployed and wasnt going to outright refuse the offer. I just received an offer letter from another company company B in the same city for 80k. I have absolutely no idea what to do. Company A is a industry leader with what I want to do in my career bicycle facility design, while company B is an industry leader in the transportation engineering design sector. Is it too late to negotiate with my current employer? Do I talk about this with my employer at all? Any advice would be helpful. Thanks!  <response>: Its too late to retroactively negotiate your compensation.That being said, there is nothing wrong with quitting and going to the other place.
