(Duluth, MN)  --  Coming off a similar dispute with Twin Cities hospitals, more than 13-hundred nurses will gather today for an informational picket in Duluth.  Nurses from St. Mary's Medical Center and St. Lukes Hospital will be outside St. Mary's picketing from noon to five to draw attention to what they believe to be inadequate staffing levels.  The nurses contracts expired June 30th and the group is currently in negotiations.  Union leader Steve Strand says in the last two years, between 150 and 200 nursing positions have been cut at St. Mary's.  Hospital officials say their nurses have the right to do an informational picket and they respect their rights.
