The supply of labour is one of the major examples of an exception to the law supply. The workers are generally concerned with high wages until a point. Once they are able to achieve a certain point they might like to dedicate their time to other activities. It means that after a particular period workers may not have a keen interest in high wages. Hence, initially, the labour supply is directly linked to the wages but after a particular point, the relation between the supply of labour and wages terms is inverse. It shows that the supply of labour refers to an exception of the law of supply.
