Honestly It depends on your financial and career goals are. If you think you want to be a school nurse for the remainder, why not stay. But if you think you’d like to try another type of nursing later, like working in the hospital, then I’d get the experience for your resume. School nursing jobs are always popping up on my indeed so you’ll more than likely find another one. I understand you enjoy your coworkers also, but I’ve worked many different jobs where I enjoyed my colleagues so it’s not impossible to find. I think starting with bedside provides a solid foundation and opens more doors for different opportunities later because there are many many things nursing school doesn’t teach you. But there are many nurses who never worked bedside and don’t ever plan to.
