The DON approved me 2 weeks vacations and I traveled outside of the USA to visit a sick family member. For reasons beyond my control that I can not describe here I could not come back on time. I took 3 weeks but I had called her to let her know about my problem. Upon my return I when to see her and she told me that I was terminated for voluntary resignation. She offered me to work per Diem. I am a very responsible person. I have been a nurse for more than 13 years and this is the first time that something like this happen to me. Also, I worry that this is going to affect me with prospective employers. Please any advice?
