The glass slab only and only produces a lateral or (sideways) shift or displacement to the direction of light. As we can observe and see below, the refraction or bending of light rays through a glass slab takes place at the two parallel and equal and opposite surfaces.
Through a glass slab, the light before coming back to the air suffers refraction two times. At the second time, the refracted ray bends away from the normal.
