I am experiencing a dilemma and would like some input. Before I became a nurse, I worked in a hospital in an non-clinical role. After a year and a half of working there a family member fell very ill and I was forced to quit immediately without a two weeks notice to care for said family member. My manager was not at work and unavailable to speak to me at the time, so I submitted my resignation in writing under her office door. When I tried to reach out to her, she would not take my calls. Later I found out that due to my not leaving with a two weeks notice, she placed me on the "do not hire" list. 3 years later, I am now an RN and have the opportunity to work as an acute dialysis nurse serving patients within the same hospital system. Will this present a problem for me working for the dialysis company? Can I still work as an employee for the dialysis company and service patients at the hospital where I am on their "do not hire" list?
