Is my employer required to follow federal and state minimum wage laws in wisconsin?

Federal laws mean "every state must comply" state laws mean the " entire state" must comply so the answer to your question is YES

Both.

Actually, state law, if it is BETTER for the employee than federal law, must be followed. No employer can do less than the federal employment laws, but if the state law provides a higher minimum wage that federal, then the state law must be followed. Current federal minimum wage is $6.55 -- no state can go below that. However, there are some job classifications within each state that do pay less. So check out your state's Department of Labor web site.

In your case, it will be a little bit complicated. In order to make FLSA (Federal Minimum Wage Law) to apply in your situation, you must be able to prove that this Subway store is not a franchise location, but a corporate store, because it is only a franchise and it does not have any business acorss stateline (interstate commerce), FLSA usually does not apply to you. See below for detail. http://www.dol.gov/compliance/guide/minwage.htm Therefore, in most of the cases, state law apply.

federal set the minimum wage however a state can choose to increase the minimum wage for that state but they cannot lower below what the federal minimum wage is companies have to follow what the state minimum wage is.
