<prompt> Human: I have been in a non-commissioned sales position for the past year in which myself and one coworker were assigned approximately equivalent geographic territories, in addition to our manager who oversaw us, and maintained some of the higher priority client relationships. My coworker recently took a position with a competing firm, and I know that she will not be replaced. As a result, myself and my manager will be dividing up the leaving colleagues territory, although I will be taking on the large majority of it.Given that my manager is losing a full salary from the budget that will not have to be replaced, and that I will be taking on significantly more responsibility, what is the best way to approach a salary negotiation? I typically dont think that I would try to negotiate anything significant after only one year on the job, but given the increased responsibility, I think that I would be missing out on a significant opportunity to negotiate a pay increase. I expect to have a fuller conversation with my manager in the next week or two to clearly define what our responsibilities will be when we lose our coworker, and think that that will be the appropriate time to bring up pay.A little background: I am a 30M, making 74kyr at this position, which I started a year ago. When should I ask for a pay increase, and how much should I ask for?  <response>: This happened to me and the first thing I did was wait 2 weeks just to see if the company was going to do anything for me wise. Nothing. I straight up asked for a raise. Nothing. 1 month later I put in my 2 weeks notice and those motherfuckers had the nerve to ask me Why? Hopefully your company is okay. Otherwise with the phrase: ..and I know that she will not be replaced. You may want to start looking yourself.
