The people of the state of Wisconsin, represented in senate and assembly, do enact as follows:
(1) Notwithstanding
2011 Wisconsin Act 32
, section
9132 (1d) (a)
, a municipal employer, as defined in section 111.70 (1) (j) of the statutes, and the representative of a collective bargaining unit containing employees of that municipal employer may enter into one memorandum of understanding that reduces the cost of compensation or fringe benefits in the collective bargaining agreement under subchapter IV of chapter 111 of the statutes that covers the employees and that is in effect on the effective date of this subsection. Such a modification is not a modification of the collective bargaining agreement for purposes of
2011 Wisconsin Act 10
, sections
9315 (1)
and (2) and
9332 (1)
or
2011 Wisconsin Act 32
, section
9332 (1c)
, (1q), and (2r), or any provisions that are substantially similar to
2011 Wisconsin Act 10
, sections
9315 (1)
and (2) and
9332 (1)
or
2011 Wisconsin Act 32
, section
9332 (1c)
, (1q), and (2r), that may be enacted under separate legislation. The memorandum of understanding entered into under this subsection remains effective for the duration of the current collective bargaining agreement and continues to be effective after the collective bargaining agreement expires until a new collective bargaining agreement takes effect except that, if the memorandum contains a provision addressing a subject that, at the expiration of the collective bargaining agreement, becomes a prohibited subject of bargaining, that provision is no longer effective. No memorandum of understanding as described in this subsection may be entered into later than 90 days after the effective date of this subsection.
