I do not know what the base rate is for LVN. However, I do not understand why no shift diff for you. Most all places pay this that I know of. Please realize you have worth. There is nothing wrong with being part time that does not make you any less then anyone else. There is nothing wrong with making your needs known. As nurses, we tend to not care for ourselves as well as we do our patients. I would start making needs known. Do not apologize for asking for a comparable setup to others. I always think that "a laborer is worthy of his/her hire" -the Bible. Nothing asked, nothing gained.
