I did a yearlong contract at a big hospital system, and I really enjoyed my time there, but my contract unfortunately expired. I now have some connections with some people in the unit and hospital system including my past manager that I have a good relationship with and can use as a reference. I saw that there was a position in a specialty I like so I applied, but I'm wondering if I should send an email to the nursing manager of that specific unit including a resume, some references, why I'm interested/qualifications/etc. Would this be considered overkill? I really want to show that I'm interested in the position but not also turn them off.
