Yes I did. The way it works is, in Pbs you go to the off days tab and select 8 or so off days. Then layer all 8 in layer 1, and 7 of them layer 2, 6 in layer 3 and then 5 in layer 4. So there's a chance you don't get all 8 off, but I did. They told me with your seniority don't select days at beginning or end of the month. I just looked at the preassignment graph and saw that feb 6-feb14 preassignments were lowest, meaning those days we were most staffed, so I selected the days then. This was in ORD this year and I was ninety something percent.
