Tardy bells, redux

With all of the meetings I have been in lately, I once again find it frustratingly necessary to implement some kind of tardy bell within my company.  This is nothing new.  I wrote on this very subject over four years ago, and nothing has changed.  People are still routinely late to meetings, often without notice or apology.  When my frustration works up to a requisite pitch, I try to calm myself by imagining a tardy-bell system like the kind I had in junior high school and high school, with middle managers, directors and senior directors dashing down the hallway at the first sounding of the bell, their coat tails trailing behind them, their ties flapping in the artificial breeze.  At least that is enough to make me smile.
