Kan. Stat. § 44-645
If after investigation the secretary of labor is of the opinion that in any occupation the wages, hours and conditions, sanitary and otherwise, are prejudicial to the health or welfare of any substantial number of the classes of employees named in this act and are inadequate to supply the necessary cost of living and to maintain the worker in health the secretary shall publish a notice, not less than once a week for four successive weeks in the Kansas register, that the secretary will on a date and at a place named in the notice hold a public meeting at which all persons will be given a hearing; and, after publication of the notice and the meeting, the secretary of labor may make and render such an order as may be proper or necessary, and require all employers in the occupation affected thereby to observe and comply with such determinations and the order.
The order shall become effective in 60 days after it is made and rendered and shall be in full force and effect on and after the 60th day following its making and rendition. The secretary of labor shall, insofar as it is practicable, mail a copy of any such order to every employer affected thereby; and every employer affected by any such order shall keep a copy thereof posted in a conspicuous place in each room of such establishment.
Whenever wages, hours, or conditions of labor have been made mandatory in any occupation, upon petition of either employers or employees, the secretary of labor may reopen the question.
