Analysis by the Legislative Reference Bureau

This bill makes changes in the subjects of collective bargaining and creates a dispute settlement procedure for classified state employes, program, project and teaching assistants of the University of Wisconsin System and assistant district attorneys.

Subjects of collective bargaining

Under the state employment labor relations act, the state and recognized or certified employe organizations are required to bargain collectively in good faith with respect to certain subjects. Currently, the subjects are wage rates, assignment and reassignment of classifications to pay ranges, determination of an incumbent's pay status resulting from position reallocation or reclassification, pay adjustments upon temporary assignment of a classified employe to duties of a higher classification or downward reallocations of a classified employe's position, fringe benefits, hours and terms and conditions of employment, except that employe occupancy of lodging provided by the state is not a mandatory subject of bargaining and demands relating to retirement and group insurance must be submitted to the employer at least one year prior to the beginning of negotiations (the consequences of failure to comply with this requirement are not set forth). The employer is prohibited from bargaining with respect to the mission and goals of state agencies; policies, practices and procedures of the civil service merit system relating to original appointments and promotions or the job evaluation system; the standard for discharge or discipline; job abandonments; grants made by the department of transportation for repayment of educational loans to minority civil engineers; family and medical leave rights that are less generous than those accorded to nonstate employes under state law; certain employe retirement contributions; interstate retirement credit reciprocity; a prohibition on the purchase of creditable service for retirement benefit purposes in order to establish entitlement to, or to affect the amount of, certain other governmental benefits; and requirements to take lie detector tests that provide fewer rights and remedies to employes than would be available in the absence of a collective bargaining agreement. The employer is directed to endeavor to obtain agreements that do not include provision for payments based upon the period of time an employe has been employed by the state ("length-of-service payments"). In addition, the amount of employe retirement and health insurance contributions (unless otherwise provided in a collective bargaining agreement), the terms of deferred compensation plans, temporary lodging allowances and provisions granting protections to certain employes who make disclosures of improper activity ("whistleblowers") are governed by statute rather than by collective bargaining agreement.

This bill provides, instead, that the state and recognized or certified employe organizations are required to bargain collectively in good faith with respect to wages, hours and conditions of employment. The bill deletes the direction to the employer concerning longevity payments. The bill also deletes the prohibited subjects and the exceptions covering retirement and health insurance contributions, deferred compensation, temporary lodging allowances and employe disclosures. Under the bill, bargaining is not required with respect to the prohibited subjects unless they are construed to fall within the purview of "wages, hours and conditions of employment".

Current law provides that a statutory provision governing retirement for state employes applies to state employes who are covered by a collective bargaining agreement unless otherwise specifically provided in the applicable collective bargaining agreement. The bill provides that provisions governing retirement for state employes that are contained in a collective bargaining agreement between the state and a labor organization representing those state employes supersede any statutory provisions that pertain to retirement, regardless of whether the matters set forth in the statutes are contained in the agreement.

Current law provides that the state may make a change in any law governing retirement for state employes and may take any action that the law permits the state to take under such a law without committing an unfair labor practice, unless an applicable collective bargaining agreement specifically prohibits the change or action. Any change in the law or any action by the state does not relieve the state of its current duty to bargain collectively with the representatives of represented employes concerning changes in provisions governing their retirement. The bill provides that it is an unfair labor practice for the state to make any change in provisions governing retirement for state employes who are represented by a recognized or certified representative unless the state first bargains collectively in good faith with the representative concerning the proposed change.

Dispute settlement procedure

The bill also creates a dispute settlement procedure for labor disputes involving employes covered by the bill. Under the procedure, the employer and any labor union representing the employes are permitted to agree upon their own dispute settlement procedures, including binding interest arbitration or authorization for a strike. If mediation fails and the parties do not agree on their own settlement procedure, the employer or the union, or the parties jointly, may request the employment relations commission to commence a process of arbitration of those issues in dispute that are mandatory subjects of bargaining (or that have been treated as such by the parties). Arbitration is required unless both parties agree to a strike. If arbitration is used, the arbitrator or panel must select the complete final offer of one of the parties without change. If arbitration is not used, each tentative agreement between the parties is submitted to the joint committee on employment relations (JCOER) and the legislature for approval in a procedure similar to that used under existing law. Currently, mediation and fact-finding (nonbinding arbitration) are the only means of dispute settlement provided in state employe labor disputes. No compulsory means of dispute settlement is currently authorized.

Under the procedure created by the bill, unless otherwise agreed by the parties, strikes are prohibited. If a strike affects the public health or safety, a court may enjoin the strike and require instead that the dispute that is the subject of the strike be submitted to arbitration. All prohibited strikes constitute an unfair labor practice and may be enjoined by a court. Any labor union engaging in a prohibited strike is to be penalized by a one-year suspension of any dues checkoff and maintenance of membership or fair-share agreement between the union and the employer. In addition, the union and its members are subject to monetary penalties for striking after an injunction is issued and special penalties for striking in violation of an arbitration award. Any party refusing to implement an award is civilly liable to the other party for costs incurred to enforce the award. Under the bill, the failure of either party to implement an award is an unfair labor practice. Although strikes by state employes are not authorized currently, the special penalties for strikes do not currently apply to state employes.

For further information see the state fiscal estimate, which will be printed as an appendix to this bill.

The commission may also provide training programs to individuals and organizations on other aspects of collective bargaining, including on areas of management and labor cooperation directly or indirectly affecting collective bargaining. The commission may charge a reasonable fee for participation in the programs.

AB361, s. 22 Section 22. 111.71 (5) of the statutes, as affected by 1993 Wisconsin Acts 16 and .... (this act), is repealed and recreated to read:

AB361,11,11 111.71 (5) The commission may provide training programs to individuals and organizations on various aspects of collective bargaining and areas of management and labor cooperation directly or indirectly affecting collective bargaining. The commission may charge a reasonable fee for participation in the programs.

AB361, s. 23 Section 23. 111.81 (1) of the statutes is amended to read:

AB361,11,20 111.81 (1) "Collective bargaining" means the performance of the mutual obligation of the state as an employer, by its officers and agents, and the representatives of its employes, to meet and confer at reasonable times, in good faith, with respect to the subjects of bargaining provided in s. 111.91 (1) with the intention of reaching an agreement, or to resolve questions arising under such an agreement. The duty to bargain, however, does not compel either party to agree to a proposal or require the making of a concession. "Collective bargaining" includes the reduction of any agreement reached to a written and signed document.

AB361, s. 24 Section 24. 111.825 (5) of the statutes is amended to read:

AB361,12,5 111.825 (5) Although supervisors are not considered employes for purposes of this subchapter, the commission may consider a petition for a statewide collective bargaining unit of professional supervisors or a statewide unit of nonprofessional supervisors in the classified service, but the representative of supervisors may not be affiliated with any labor organization representing employes. For purposes of this subsection, affiliation does not include membership in a national, state, county or municipal federation of national or international labor organizations. The certified representative of supervisors may not bargain collectively with respect to any matter other than wages and fringe benefits as provided in s. 111.91 (1).

AB361, s. 25 Section 25. 111.84 (1) (b) of the statutes is amended to read:

AB361,12,23 111.84 (1) (b) Except as otherwise provided in this paragraph, to To initiate, create, dominate or interfere with the formation or administration of any labor or employe 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 specifically prohibits the change or action. No such change or action affects the continuing duty to bargain collectively regarding the Wisconsin retirement system under ch. 40 to the extent required by s. 111.91. It is not an unfair labor practice for the employer to reimburse state employes at their prevailing wage rate for the time spent during the employe'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.

AB361, s. 26 Section 26. 111.84 (1) (d) of the statutes is amended to read:

AB361,13,10 111.84 (1) (d) To refuse to bargain collectively on matters set forth in s. 111.91 (1) with a representative of a majority of its employes 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 employes 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.

AB361, s. 27 Section 27. 111.84 (1) (g) of the statutes is created to read:

AB361,13,13 111.84 (1) (g) To fail to implement an arbitration award lawfully made under s. 111.885.

AB361,13,22 111.84 (2) (c) To refuse to bargain collectively on matters set forth in s. 111.91 (1) with the duly authorized officer or agent of the employer which is the recognized or certified exclusive collective bargaining representative of employes specified in s. 111.81 (7) (a) in an appropriate collective bargaining unit or with the certified exclusive collective bargaining representative of employes specified in s. 111.81 (7) (b) or (c) 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.

AB361, s. 29 Section 29. 111.84 (2) (e) of the statutes is amended to read:

AB361,14,3 111.84 (2) (e) To Except as authorized in s. 111.885, to engage in, induce or encourage any employes to engage in a strike, or a concerted refusal to work or perform their usual duties as employes.

AB361, s. 30 Section 30. 111.84 (2) (g) of the statutes is created to read:

AB361, s. 33 Section 33. 111.88 of the statutes is repealed.

AB361, s. 34 Section 34. 111.885 of the statutes is created to read:

AB361,14,22 111.885 Methods for peaceful settlement of disputes. (1) Notice of commencement of contract negotiations. For the purpose of advising the commission of the commencement of contract negotiations, whenever the employer or a labor organization certified or recognized to represent employes under this subchapter requests the other party to reopen negotiations under a binding collective bargaining agreement, or the parties otherwise commence negotiations if no such agreement exists, the party requesting negotiations shall immediately notify the commission in writing. Upon failure of the requesting party to provide such notice, the other party may so notify the commission. The notice shall specify the expiration date of the existing collective bargaining agreement, if any, and shall set forth any additional information that the commission may require on a form provided by the commission.

AB361,15,4 (2) Presentation of initial proposals; open meetings. The meetings between parties to a collective bargaining agreement or proposed collective bargaining agreement under this subchapter that are held for the purpose of presenting initial bargaining proposals, along with supporting rationale, shall be open to the public. Each party shall submit its initial bargaining proposals to the other party in writing. Failure to comply with this subsection is not cause to invalidate a collective bargaining agreement under this subchapter.

AB361,15,8 (3) Mediation. The commission or its designee shall function as mediator in labor disputes involving employes, upon request of one or both of the parties or upon initiation of the commission. The function of the mediator is to encourage voluntary settlement by the parties. No mediator has the power of compulsion.

AB361,15,13 (4) Grievance arbitration. Parties to a dispute pertaining to the meaning or application of the terms of a written collective bargaining agreement under this subchapter may agree in writing to have the commission or any other appropriate agency serve as an arbitrator or may designate any other competent, impartial and disinterested person to so serve. Such proceedings are governed by ch. 788.

AB361,15,22 (5) Voluntary impasse resolution procedures. In addition to the other impasse resolution procedures provided in this section, the employer and labor organization may at any time, as a permissive subject of bargaining, agree in writing to a dispute settlement procedure which is acceptable to the parties for resolving an impasse over terms of any collective bargaining agreement under this subchapter, including authorization for a strike by employes or binding interest arbitration. A copy of the agreement shall be filed by the parties with the commission. If the parties agree to any form of binding interest arbitration, the arbitrator shall give weight to the factors enumerated in sub. (7).
