<prompt> Human: Ive been in my new job for almost 5months and thoroughly enjoy it. Ive known for some time that I am getting underpaid tried negotiating a higher salary but was told there wasnt any room in the budget but didnt realize how bad until today. Today I found out that one coworker who is basically my assistant and another coworker in my department who is responsible for 13 of the amount of work I do and started after me both make more than me. When can I reasonably approach my bossupper management for a raise? How can I ask for a raise without throwing anyone else under the bus for making more yet being responsible for far less? Any advice anyone can give would be greatly appreciated. Update: Thanks all for the responses. I wanted to clear up a couple things: 1. Im not expecting a raise immediately after only being there for 5 months but I would like to be ready to have the conversation when the time is right hence me asking When can I reasonably approach my bossupper management for a raise?2. Yes I generate quite a bit of revenue for the company so even after only 5 months Ive proven my worth and will continue to do so3. Yes, I know for a fact that they both have less responsibilities than me  <response>: Start looking for a new job now.Otherwise you will have accepted managements position that you are a second class empoyee for the rest of your time there. You will never advance!
