I'M ALMOST ALWAYS against unions when they threaten strikes, but in this case I'm almost in favor of the union. PEPCO, the electric power provider for most of Washington DC is being threatened by the local union with a possible strike. Since PEPCO has been vilified over the years by local residents for outages caused by trees falling that they won't let PEPCO trim, I'm leaning toward allowing a strike that would give the residents of DC their just desserts.
