Back in '08 my area had the heaviest snowfall in recorded history occur for 2 weeks prior to Xmas, and our entire region was paralyzed.
Had we been asked to work on Christmas day, I might have considered it. in that situation, there really wasn't anything that management could have realistically done to solve the backlog of packages.
This year, I will be bringing back several hours worth of stops at 10:00 PM on Christmas Eve, not due to weather or other events beyond management's control but because some IDIOT made a business decision to intentionally set us up to fail by grossly understaffing the operation. If they think for one minute that I will give up time with my family on Christmas in order to rescue them from their utterly incompetent decision making, they have another thing coming.
I feel bad for the customers who wont get their packages, but its not my fault. This is one of those situations that calls for some "tough love" on our part. Consequences are natures way of forcing stupid people to stop making stupid decisions, and UPS management needs to accept the consequences for the asinine choices they made this year. I will bust my ass for 60 hours a week without complaint for the duration of peak, but on Christmas Day I am staying home. Period.
