Do I need rebar for small concrete slab?

You do not need rebar for any slab if you make it thick enough and space the joints properly. Rebar in jointed pavement is there to counter the cupping effect of thermal expansion. I always recommend the use of rebar or at least rewire. Any concrete slab can crack.
