Night shift scheduling drove me crazy; WorkBuddy saved my life

Last Thursday night shift, the head nurse tossed me next month's schedule and said, "You're young, so you should take on more work." I stared at that Excel sheet for ten minutes until my eyes blurred. 14 nurses, three shifts (N-shift, P-shift, day shift), can't have anyone working N-shifts for three consecutive days, everyone needs at least one day off per week, and senior staff can't be paired incorrectly with junior ones. Manually dragging cells around, I finally came up with a plan by 1:30 AM, only to get sent back by the head nurse saying, "Little Liu has a professional title exam this month, no N-shifts for her," forcing me to start over.
