Simple answer....................first they actually get a deduction on taxes, as it doesn't come under their own employees. #2: exmaply, OR has just had a nurse quit, when they do hire someone they will get minimum of a three month orientation, they not to have a body in that slot right away, so agency can fill in. #3: If the facility is in an area where the census varies by season, it is much more cost effective to use agency than keep someone on the books year round. #4: If the census luctuates greatly on a day to day basis on the unit, especially critical care areas, it is easier to use agency when they need them, then have to have someone always take a low census day.
Just a few reasons...............
