Kroger Benefits - School project questions

I need some specific info about Kroger's pay and benefits, for the southeast in particular. Here it is:
-What is a cashier's starting hourly pay?
-Do they make more depending on how long they work at a store? How much more and over what time period?
-How much vacation do they get per year?
-How many sick days per year?
-What PAID holidays do they get off?
-How much do they pay for insurance each month if only the employee receives coverage? For employee and spouse? For employee spouse and child?
-What do store managers and assistant managers make on average?
-Are their vacation days, sick days, and holiday benefits different from cashiers?
-Are their insurance benefits the same as cashiers?

This is for a study we're doing in school about local grocery stores. I know it's a lot of questions, but any info will help. Thanks
