ST. PAUL, Minn. (AP) — The Minnesota AFL-CIO is airing TV and radio ads across Minnesota against a constitutional amendment under consideration at the Capitol that would curb union strength.

The ads started airing on Tuesday, the day after a Senate committee approved the right to work amendment which if passed by voters would make union membership voluntary in Minnesota. Some Republicans in the Legislature are hoping to put the issue before voters statewide in November though it’s not yet seen as a certainty.

The AFL-CIO ad features firefighters, a nurse and other union employees. It calls the proposal unfair, unnecessary and unsafe. In addition to airing statewide, targeted versions of the ad will be aired in the districts of Republican senators from Bemidji, Willmar, Red Wing, Rochester, St. Cloud and Eagan.
