Kind of a touchy subject, as those who celebrate Christmas in the US and are 'old school', like myself, may tend to feel that we've abandoned respect for our traditions in favor of instant gratification ... and those who don't celebrate may feel they shouldn't be inconvenienced. Personally, you'll never see a promotion from me on Christmas or any other major holiday, simply out of respect for the traditions I grew up with. It can wait till the next day, IMHO ...
