The commission shall certify exclusive bargaining representatives in accordance with the procedures specified in this section.

(1) No question concerning representation may be raised within one year following issuance of a certification under this section.

(2) If there is a valid collective bargaining agreement in effect, no question concerning representation may be raised except during the period not more than ninety nor less than sixty days prior to the expiration date of the agreement: PROVIDED, That in the event a valid collective bargaining agreement, together with any renewals or extensions thereof, has been or will be in existence for more than three years, then a question concerning representation may be raised not more than ninety nor less than sixty days prior to the third anniversary date or any subsequent anniversary date of the agreement; and if the exclusive bargaining representative is removed as the result of such procedure, the collective bargaining agreement shall be deemed to be terminated as of the date of the certification or the anniversary date following the filing of the petition, whichever is later.

(3) An employee organization seeking certification as exclusive bargaining representative of a bargaining unit, or faculty members seeking decertification of their exclusive bargaining representative, must make a confidential showing to the commission of credible evidence demonstrating that at least thirty percent of the faculty in the bargaining unit are in support of the petition. The petition must indicate the name, address, and telephone number of any employee organization known to claim an interest in the bargaining unit.

(4) A petition filed by an employer must be supported by credible evidence demonstrating the good faith basis on which the employer claims the existence of a question concerning the representation of its faculty.

(5) Any employee organization which makes a confidential showing to the commission of credible evidence demonstrating that it has the support of at least ten percent of the faculty in the bargaining unit involved is entitled to intervene in proceedings under this section and to have its name listed as a choice on the ballot in an election conducted by the commission.

(6) The commission shall determine any question concerning representation by conducting a secret ballot election among the faculty members in the bargaining unit, except under the following circumstances:

(a) If only one employee organization is seeking certification as exclusive bargaining representative of a bargaining unit for which there is no incumbent exclusive bargaining representative, the commission may determine the question concerning representation by conducting a cross-check comparing the employee organization's membership records or bargaining authorization cards against the employment records of the employer. A determination through a cross-check process may be made upon a showing of interest submitted in support of the exclusive bargaining representative by more than fifty percent of the employees; or

(b) If the commission determines that a serious unfair labor practice has been committed which interfered with the election process and precludes the holding of a fair election, the commission may determine the question concerning representation by conducting a cross-check comparing the employee organization's membership records or bargaining authorization cards against the employment records of the employer.

(c) The commission may adopt rules to implement this subsection (6).

(7) The representation election ballot must contain a choice for each employee organization qualifying under subsection (3) or (5) of this section, together with a choice for no representation. The representation election shall be determined by the majority of the valid ballots cast. If there are three or more choices on the ballot and none of the three or more choices receives a majority of the valid ballots cast, a runoff election shall be conducted between the two choices receiving the highest and second highest numbers of votes.

(8) The commission shall certify as the exclusive bargaining representative the employee organization that has been determined to represent a majority of faculty members in a bargaining unit.
