Hawaii Revised Statutes Division 1. Government § 377-4.6

(a) When an employee, group of employees, or any individual or labor organization acting on their behalf, files a petition alleging that a majority of employees in a unit appropriate for the purposes of collective bargaining wish to be represented by an individual or labor organization for those purposes, the board shall investigate the petition. If the board finds that a majority of the employees in a unit appropriate for bargaining have signed valid authorizations designating the individual or labor organization specified in the petition as their bargaining representative, and that no other individual or labor organization is currently certified or recognized as the exclusive representative of any of the employees in the unit, the board shall certify the individual or labor organization as the representative without directing an election similar to that under section [377-1].

(b) The board shall adopt rules governing the certification of an exclusive representative under this section and shall have the final determination on any controversy concerning the eligibility of an employee to sign an authorization card and the validity of an employee's signature on an authorization card.

(c) For the purposes of this section, the term “employee” means an employee as defined in section 377-1; provided that the employee is employed by an employer with an annual gross revenue of more than $5,000,000.
