I've been in my current position for about 3 years. Initially I started out as a solo in-house graphic designer working on web and social media graphics but with time my responsibilities grew to include photo editing, animation and recently web development.
Currently my work is mainly focused on web development but my title hasn't changed. I still help with the odd banner/resizing/image edit etc.
As per the question title, my manager is looking to hire a new person who will do essentially my job but focusing on the graphic design aspect.
I came across the job advert and saw that the starting wage is higher than what I am paid at the moment.
I'm not sure how to go about asking my manager about this as I understand she doesn't respond well when asked about pay rises. Also I would not want to make a wrong move and put myself in a negative light.
