The Secretary of Labor, with the approval of the Governor, may establish such division or divisions as may, in his discretion, be necessary or desirable for the administration or enforcement of any law or any rule or regulations with which the Department of Labor is charged or the performance of any of its functions or duties. Each division in the Department of Labor shall be headed by and be under the direction, supervision and control of an officer who shall be designated as the chief of such division. All chiefs of divisions shall be appointed by the Secretary of Labor, subject to the provisions of the Merit System. Before entering upon the discharge of their duties, such chiefs of divisions shall take the constitutional oath of office. Each of such officers shall devote his full time to his official duties and shall hold no other lucrative position while serving as such. It is one of the purposes of this chapter to coordinate, in one division of the Department of Labor, unemployment compensation and employment service. Unemployment compensation and employment service shall be in one division of the Department of Labor under the direction of the chief of said division. Within said division, but subordinate to the chief thereof, there shall be a full-time salaried director of unemployment compensation and a full-time salaried director of employment service. The salaries of said chief and directors shall be paid solely from federal grants and shall be comparable to those paid similar officers in comparable states, notwithstanding any limitation or maximum in any other law.
