I've been with my company for some years, promoted two years ago and a pay rise then. I have been told by management that I'm doing really well and I know that I am paid right at the bottom end of the scale for my level, it goes up another 40k. Plus two people who work for me (who started as freelancers) get paid more than me, one significantly. Should I ask for a pay rise? Have never asked before and don't want to appear cheeky but I am managing a huge piece of work for the business and hope I am valued.
