When I fill out a job application, I read the fine print. If you have had a lot of short term positions, you may want to have them on a separate piece of paper to attach to the application.

A lawyer advised me about this once! Reasons for leaving can be, position eliminated, downsized, personal reasons, relocated, pursue position as a...I am seeing more and more employers interested in background checks and wanting references from coworkers ( as opposed to employers). People move around a lot in nursing, it can be hard to locate supervisors. Where as giving personal references, shows teamwork, and can be easier to reach than supervisors. HR can only say so much, i.e.: position and dates of employment. I hope this wasnt too much information!!!
