Applying for another internal job

[ilyah]

Hi, so I just made over a year working as a Med/Surg acute care RN in a hospital. I know now that I want to move away from the bedside, but have had absolutely no luck getting even interviews for anything away from the bedside for the past couple months of applying. Well, a new job posting just opened up internally, for a case management position. The problem is, that I am 1 year short of the required experience. Is it worth submitting interest and letting my manager know on the off chance I get an interview? I'm worried that if I don't get the job, that my boss will now know I have one foot out of the unit and will either treat me differently/at the worst fire me. Thoughts?
