I have worked for a multinational company for 3 months now, but we are only 4 people in my local department (including the manager).
I am not unhappy with my salary, but it has come to my attention that the two others - excluding the manager, are having a higher salary than me, relative to our experience and education, and for this reason I would like to get a salary discussion so that I get on par with my coworkers. It should be noted that me and my coworkers are having complete different backgrounds and work areas. This gives me two questions:
1) There is nothing written in my contract regarding when we are having salary discussions. So, what is the best way for me to approach my manager, about having a salary discussion?
2) When we are at the salary discussion, is it obviously a bad approach to mention coworkers salary, when negotiating a raise. My question is, how I should approach this discussion when I am not underpaid compared to industry standards, but just compared to my coworkers?
EDIT:
I dont see how 1) is explained in the link to the duplicate question, and as thus, I do not think it should have been closed of that reason.
