Well I can pass on some info based on the places I have worked.
Baptist- Good working environment, so\so pay, poor management, low self esteem company, good benefits, good educational dept., parking sucks.
Baptist West- Do not apply here, poor working conditions, no security force on campus (because it's faragutt and police are not pretty), poor management, internists that kill patients in their ICU on a daily basis, and no job security.
Parkwest- New clean hosptital, ok pay, nice cafe makes working there a plus, a busy 40 bed ER keeps the Unit and OR hopping. Poor benefits though, and parking sucks there too. But my choice of the three.
Knoxville however is starting to look like Memphis (remember that lawsuit against the hospitals there) UT, St Marys, Covenant, and Baptist have all gotten together and compared pay rates in an effort to keep base pay rates low. I was at a conference in KY one time and they were all sitting together at the same vendor booth. What do you know.. all the hosptials offered the same $17.10 starting rate for new grads...
