OAR 115-025-0021
Showing of Interest Requirements

(1) Many petitions must be supported by a valid showing of interest.
(2) A petitioner can fulfill the showing of interest requirement by submitting authorization documents (typically cards) signed by eligible employees. An authorization document must, at a minimum, contain the following:
(a) The employee’s name, typed or legibly printed;
(b) The employee’s signature;
(c) The date of the employee’s signature;
(d) A statement that the employee designates the named labor organization as the employee’s exclusive representative for purposes of collective bargaining with the employee’s employer (if applicable); and
(e) A statement that the employee understands how the authorization document may be used. The statement must be consistent with the type of petition being filed. Model language for card check petitions is provided below, in section (4) of this rule.
(3) An authorization document must be signed and dated within the 180-day period before the petition is filed.
(4)(a) The Board has developed the following model language that may be used for the showing of interest for a card check petition (to certify a new bargaining unit or to add unrepresented employees to an existing unit):
(b) The authorization document may use different language than subsection (4)(a) of this rule, but the document must include the same information for the authorization to be valid.
(5)(a) When authorization cards are used for the showing of interest, the petitioner should arrange the cards alphabetically by last name. Authorizations that do not substantially comply with this rule will not be counted.
(b) The Board will accept electronic copies of showings of interest with a petition as sufficient to initiate the Board’s processes, but petitioners must provide original documents to the Board within ten (10) days of the filing of the petition.
(6)(a) The showing of interest submitted under these rules will not be furnished to any of the parties except the party that filed the showing of interest, which may examine cards or petitions when signatures are deemed invalid.
(b) The showing of interest will be destroyed when the file is closed unless the party filing the showing of interest requests that its showing of interest be returned. The Board will return the original showing of interest to a petitioner upon request if the petition is withdrawn.
