Minneapolis, MN (Minnesota News Network)  --  Forty-eight-hundred nurses return to the job at five Allina Health hospitals in the Twin Cities this (Sunday) morning after completing a seven-day strike.

The union and the hospitals have no new negotiating sessions scheduled, for now.  The two sides have reached a stalemate over health insurance.  Two-thirds of the nurses voted to reject Allina's contract offer June 6th.

A second strike is possible, but it would require another failed negotiating attempt and another "thumbs down" vote by union members at all five hospitals.
