I have been with my current employer for Two and a half years, two male counterparts whom arrived after me and do not put in nearly the same effort or hours that I do. Both have taken credit for work I have done and are paid more despite me having more experience. How do I ask for a raise and bring to light my efforts and hard work, without bashing them and coming out as bitter? I will always work hard because I am accountable for my actions and work ethic. However I would at least like to be equally compensated and I found out about their pay grade, purely by chance so it’s information I was not intended to have.
