Hey Bob,
I too have been simular situations....
As the on-call guy...
Almost the same...
Grocery store due to Tranny explosion right after I walked in to find the neutral melted, (They stacked pallets on top of it, and all around it.) really lucky I wasn't standing there as I was off telling the manager he had to shut down the store at 7PM. Had to pull guys back from all over the place and work all night. We were the first there of 5 EC's they called, as they called EVERYONE!
On the Boss-less thing too...
PM passed on suddenly, and it took a year to find a suitable replacement. It was like circus for some time. Everyone had to pull thier on wieght, unfortunatley, at times in opposite directions. But it worked out...
Anyway, hang in there, and Merry X-mas,
Mark
