I work for a software company and was originally hired as a graphic designer. My role was to design for both print collateral and web. Since my time at the company I have transitioned to designing their products (e-learning based). Since my work has changed I saw no salary change, in fact they still call my their "graphic designer" which stings a little because that's not me. Anyways, I'm the only designer at this company of nearly 100 employees now. The company is growing and I feel my role is being under compensated.
Should I ask for a salary increase? Currently I make what's considered the national median graphic designer's salary but I feel I should be making a UI designer's salary at the very least which is roughly 20k more a year(USD).
How do I approach something like this? Should I bother asking risking my job? I'd rather not risk losing my position by asking for more compensation. Anyone have any experience in this dilemma? Any help is appreciated.
