Theses days most hospital facilities require staff apply online to open posted positions. . There has to be an available PRN position on your unit in order for you to request that status.
Recently, I've had a staff member submit resignation from a FT position to accept another job which I immediately posted. Another perdiem clerk had submitted resignation week before, position was posted, applicant interviewed, selected and sent to HR to start hiring process.
Well, the FT staffer was very upset with me this week that they had applied a few days later (along with 80 other persons), that I hadn't hired them for the perdiem position.
If they had come to me and discussed looking for a job in IT and asked if they could stay on, would have considered request. Once resignation is formally submitted to HR and my boss, I've been taught by HR need to accept and allow person to move on.
Best wishes on your new job..... Grn Tea does write great letters and provide sound advice to our members.
