Whenever a mechanic, artisan, miner, laborer, servant or employee brings an action for wages earned and due and owing according to the terms of the employment, and establishes by the decision of the court or jury that the amount for which he or she has brought the action is justly due and owing, and that a demand was made in writing at least 3 days before the action was brought, for a sum not exceeding the amount so found due and owing, then the court shall allow to the plaintiff a reasonable attorney fee of not less than $10, in addition to the amount found due and owing for wages, to be taxed as costs of the action.
