Been there, done that (well actually a PhD after 20+ years experience). It depends on your motivation, is it to learn a lot about something you are interested in or is it to earn more money? To clarify, masters degrees are about advanced learning about a specialised topic. Typically there is a capstone project which requires some research and a thesis. But for extensive research into a topic you pursue a PhD. The criteria being that you make a contribution to the existing body of knowledge. Whilst with a masters you learn the body of knowledge as it stands at that time of your studies. If you expect to earn more, then you would first need to research the jobs in your area of interest and see if any require a masters degree. Some companies prefer industry experience over academic credentials and others are the other way around. It wouldn't hurt to apply for some jobs in your area of interest and see what the feedback is.
