More than 1,300 nurses from two Twin Cities Fairview hosptials are preparing to return to work Friday. The nurses voted to approve a new contract yesterday after three weeks on strike. Colleagues from 11 other Twin Cities hospitals avoided a strike when they reached settlement agreements before June 3rd. Joanne Disch is the director of the Densford International Center for nursing leadership at the University of Minnesota. She says all the contracts are unique in how they approach the issue of staffing shortages.
