(1) The Legislature hereby declares and determines that the employees of the several offices, committees, and other divisions of the Legislature are and shall continue to be groups of employees employed by the Legislature to perform such services as may be provided by law, by rule of the respective house, or directed by the joint committee, whichever is applicable. Such offices, committees and divisions are not agencies of government within the intent of the Legislature as expressed in chapters 216 and 287.
(2) Agencies of the executive branch shall have no power to determine the number or fix the compensation of legislative employees or exercise any manner of control over them. The selection of such employees, the determination of their qualifications and compensation, and the establishment of policies relating to their work, including hours of work, leave, and other matters, shall be the sole prerogative of the Legislature.
