are your administrators telling you that you will be hired as a nurse case manager upon graduation? i know that degrees outside of nursing allow for direct case management jobs without clincial work experience. however, those jobs are non-nursing jobs
and they are veyr very low paying (i, know because i worked them prior to nursing)!
in my job search
i see that nursing jobs in case management require clinical work experience. also, i have never ever seen a degree in case management as a requirement for nurses. in fact, the jobs i have seen require or prefer a bsn plus years of clinical work experience. therefore, i think you may find the answer to your questions in reading job descriptions posted by the facilities near where you plan to live when you graduate.
plus, keep in mind that schools tend to create degrees that do not necessarily correspond with the job market. academia creates degrees that correspond with student interest. so, a degree in case management may be helpful for nurses, but it may not necessarily get you a job over nurses who do not have that degree, but have a bsn with way more clincial work experience. gl!
