I am implementing an internship program for high school students in central Florida.  the focus of the program is to expose/preview career options upon graduating from high school through continuing education.  hopefully the intern will have a better perspective of what they want before they get to college... in a nut shell.  one of the businesses I was recruiting explained they wouldn't take on an intern unless they were insured.  they didn't know the "why" or the "how", but said unless they (the intern) were insured, no dice.  can anyone give me the rhyme & reasons for this, and what type of insurance is needed.  

Thanks in advance

It seems to me most businesses provide the appropriate insurance on their employees. I need to know the particular business, and what the intern would be doing. I think it would have to be a pretty unusual business to expect the employees to get their own insurance.
