With two days to go before a planned strike, the Minnesota Nurses Association is going public with stories of alleged poor patient care to back its assertion that hospitals are dangerously understaffed. The union, which says hospital staffing is at the core of its dispute with management, has scheduled a news conference to tell some of those stories. "We don't think the general public truly understands just how unsafe things are inside our hospitals, and that it's getting worse," said Cindy Olson, a member of the nurses' negotiating team.
