I was wearing a walking cast on my broken right foot toward the end of my tenure as an administrative assistant at the University of Michigan Ross School of Business. At work one day, when I knew I was tendering my resignation but had not yet announced it, I was clunking into our “hub” from my office down the hall. The hub was a room that had multiple functions: mail room, kitchen, copy room, and a place where people touched base, shared a greeting, or had a chat. On this day one of my co-workers walked in at the same time as I and greeted me with, “How long do you have?”
