Hi there,
All wood will react to varying temperatures/moisture content and by laminating both surfaces you will balance the reaction. If only one surface is laminated, the other surface will have a different expansion/contraction rate.
Admittedly, with hard wood the movement is less and in a stable workshop probably minimal. My router fence is made from oak and not laminated and shows no signs of movement at all and the table is veneered MDf simply sealed and edged with oak and it is still true.
