They constantly want you to work because they are short staffed. They are constantly short staffed because no one wants to stay. We had multiple staff quit during orientation because of the culture. People that stayed through orientation, were constantly looking, and would quit eventually for better pay, better benefits, and most often - a better culture.
Pay - one could travel to another city less than an hour away for as much as $10 more an hour. In the same town, you can get paid $3-5 more working long term care.
Benefits - better pretty much anywhere you go.
Advancement - good if you are good friends with the "right" people, qualifications don't matter.
Management - petty, plays favorites, and much of the time unqualified for the job. Follow FOCUS values when it is convenient. Passes the buck whenever possible. Lies to cover themselves, willing to throw anyone under the bus to save their own skin.
Culture - pretty much a cross between high school, Scrubs the television show, and Grey's Anatomy the television show - all on a low buget.
Easy to get hired, to get some experience.
Pretty much everything else.
