Talks lasted until 1 o’clock this morning. And both sides made changes in their contract demands. But there’s still no agreement in the nurses’ dispute with 14 Twin Cities hospitals. Both sides issued statements early this morning, detailing the offers they made. The hospitals say they backed off their call for pension cuts, as long as certain conditions were met — including an immediate withdrawal of a strike notice by the union. The hospitals also answered concerns about staffing levels by offering to set up a task force on nurse workloads. But the Minnesota Nurses Association says a similar task force idea “failed miserably” when urged by the legislature last year. And the union says it softened its pay demands. But little progress was reported and no new talks are scheduled. So both sides are making preparations for a walkout next Tuesday. All day today union is holding strike preparation meetings for nurses at its headquarters in St Paul.
