You can't make a concrete encased electrode using a slab. The rebar or copper wire must be in a footing or foundation.
In my opinion it would depend on the function of the slab. Parking areas and sidewalks would not be foundations (although if you turn one edge down it might qualify as having a footer) . A base for a specific piece of equipment or a pad for a stand-up service would meet the dictionary definition of a foundation.
Per m-w.com: foundation -- underlying base or support
Per dictionary.com: foundation -- the natural or prepared ground or base on which some structure rests (structure is "something built or constructed")

How does the poly under the footer make a difference? The rebar is still in concrete, underground; so it is still in direct contact with the earth, no?And in direct earth contact. Poly under the footer doesn't cut it.
Informational Note: Concrete installed with insulation, vapor barriers, films or similar items separating the concrete from the earth is not considered to be in ?direct contact? with the earth.
If you are going to use definitions you must use them out of the code books not the dictionary, unless there is no definition of that term in the code books.
