111.84111.84 Unfair labor practices.

111.84(1)(1) It is an unfair labor practice for an employer individually or in concert with others:

111.84(1)(a)(a) To interfere with, restrain or coerce employees in the exercise of their rights guaranteed in s. 111.82.

111.84(1)(b)(b) Except as otherwise provided in this paragraph, to initiate, create, dominate or interfere with the formation or administration of any labor or employee organization or contribute financial support to it. Except as provided in ss. 40.02 (22) (e) and 40.23 (1) (f) 4., no change in any law affecting the Wisconsin retirement system under ch. 40 and no action by the employer that is authorized by such a law constitutes a violation of this paragraph unless an applicable collective bargaining agreement covering a collective bargaining unit under s. 111.825 (1) (g) specifically prohibits the change or action. No such change or action affects the continuing duty to bargain collectively with a collective bargaining unit under s. 111.825 (1) (g) regarding the Wisconsin retirement system under ch. 40 to the extent required by s. 111.91 (1). It is not an unfair labor practice for the employer to reimburse an employee at his or her prevailing wage rate for the time spent during the employee’s regularly scheduled hours conferring with the employer’s officers or agents and for attendance at commission or court hearings necessary for the administration of this subchapter. Professional supervisory or craft personnel may maintain membership in professional or craft organizations; however, as members of such organizations they shall be prohibited from those activities related to collective bargaining in which the organizations may engage.

111.84(1)(c)(c) To encourage or discourage membership in any labor organization by discrimination in regard to hiring, tenure or other terms or conditions of employment. This paragraph does not apply to fair-share or maintenance of membership agreements.

111.84(1)(d)(d) To refuse to bargain collectively on matters set forth in s. 111.91 (1) or (3), whichever is appropriate, with a representative of a majority of its employees in an appropriate collective bargaining unit. Where the employer has a good faith doubt as to whether a labor organization claiming the support of a majority of its employees in appropriate collective bargaining unit does in fact have that support, it may file with the commission a petition requesting an election as to that claim. It is not deemed to have refused to bargain until an election has been held and the results thereof certified to it by the commission. A violation of this paragraph includes, but is not limited to, the refusal to execute a collective bargaining agreement previously orally agreed upon.

111.84(1)(e)(e) To violate any collective bargaining agreement previously agreed upon by the parties with respect to wages, hours and conditions of employment affecting employees, including an agreement to arbitrate or to accept the terms of an arbitration award, where previously the parties have agreed to accept such award as final and binding upon them.

111.84(1)(f)(f) To deduct labor organization dues from the earnings of a public safety employee, unless the employer has been presented with an individual order therefor, signed by the public safety employee personally, and terminable by at least the end of any year of its life or earlier by the public safety employee giving at least 30 but not more than 120 days’ written notice of such termination to the employer and to the representative labor organization, except if there is a fair-share or maintenance of membership agreement in effect. The employer shall give notice to the labor organization of receipt of such notice of termination.

111.84(1)(g)(g) To use any moneys received for any purpose to discourage, to train any supervisor, management employee, or other employee to discourage, or to contract with any person for the purposes of discouraging, employees in the exercise of their rights guaranteed under s. 111.82.

111.84(2)(2) It is an unfair labor practice for an employee individually or in concert with others:

111.84(2)(a)(a) To coerce or intimidate an employee in the enjoyment of the employee’s legal rights, including those guaranteed under s. 111.82.

111.84(2)(b)(b) To coerce, intimidate or induce any officer or agent of the employer to interfere with any of the employer’s employees in the enjoyment of their legal rights including those guaranteed under s. 111.82 or to engage in any practice with regard to its employees which would constitute an unfair labor practice if undertaken by the officer or agent on the officer’s or agent’s own initiative.

111.84(2)(c)(c) To refuse to bargain collectively on matters set forth in s. 111.91 (1) or (3), whichever is appropriate, with the duly authorized officer or agent of the employer which is the recognized or certified exclusive collective bargaining representative of employees specified in s. 111.81 (7) (a) in an appropriate collective bargaining unit or with the certified exclusive collective bargaining representative of employees specified in s. 111.81 (7) (ar) to (f) in an appropriate collective bargaining unit. Such refusal to bargain shall include, but not be limited to, the refusal to execute a collective bargaining agreement previously orally agreed upon.

111.84(2)(d)(d) To violate the provisions of any written agreement with respect to terms and conditions of employment affecting employees, including an agreement to arbitrate or to accept the terms of an arbitration award, where previously the parties have agreed to accept such awards as final and binding upon them.

111.84(2)(e)(e) To engage in, induce or encourage any employees to engage in a strike, or a concerted refusal to work or perform their usual duties as employees.

111.84(2)(f)(f) To coerce or intimidate a supervisory employee, officer or agent of the employer, working at the same trade or profession as the employer’s employees, to induce the person to become a member of or act in concert with the labor organization of which the employee is a member.

111.84(3)(3) It is an unfair labor practice for any person to do or cause to be done on behalf of or in the interest of employers or employees, or in connection with or to influence the outcome of any controversy as to employment relations, any act prohibited by sub. (1) or (2).

111.84(4)(4) Any controversy concerning unfair labor practices may be submitted to the commission as provided in s. 111.07, except that the commission shall fix hearing on complaints involving alleged violations of sub. (2) (e) within 3 days after filing of such complaints, and notice shall be given to each party interested by service on the party personally, or by telegram, advising the party of the nature of the complaint and of the date, time and place of hearing thereon. The commission may in its discretion appoint a substitute tribunal to hear unfair labor practice charges by either appointing a 3-member panel or submitting a 7-member panel to the parties and allowing each to strike 2 names. Such panel shall report its finding to the commission for appropriate action.
