Right I’m not talking about your current salary I’m talking about the potential for your salary to grow in the future. I’m not familiar with how the medical field is structured and it sounds like you’re saying it may work opposite from how one would expect. I work in Tech sector and typically in order to get a better paying position (career advancement ) we’re looking to become more specialized and get more licenses or certifications that employers need, rather than going into a less specialized position that can be done by “anyone”.
