Of course, why would the Republican be cooperative where unions are concerned???

Contract agreements between Minnesota and its public sector unions typically sail through the Legislature. This year, however, those deals may get caught up in a broader fight over union dues and political activities.

House Republicans this spring have altered the traditional process of putting all the two-year contracts up for a single vote. Instead, they've spread ratification votes across several bills, and the bill they've crafted for the state's biggest unions is coming with some serious strings attached. It calls for limiting vacation cash outs, making union dues optional and relieving the state of the duty to collect fees.
