When the price of the product increases by 50%, why does the employee's salary portion stay the same? Ali Nasiri Ajdam, faculty member of Alma Tabatbay University: the ratio between the labor cost and the manufacturer's sales must be maintained from April until today; That is, if the selling price and production costs increase, the wages of the workforce must also increase in proportion to the same ratio. This increase does not necessarily harm the manufacturer, because the price of the products and other costs have also increased. Other costs cannot be increased according to inflation, but the employee's salary can be kept constant.
