Do you really think it is that?

Do you really think Butterball significantly increases their staffing around the last Thursday in November?
Which do you think is easier to predict? How many turkeys you are raising on your farms, and therefore need to stuff into sacks, or how many companies out there may or may not use your services and how many presents people may or may not buy this year as the economy and holiday retail cycles over the past few years? Shipping an unknown quantity of items all over the United states is JUST LIKE retailers staffing registers at Target and Kohl's, right?
Just think, if UPS hired a few of the folks here to manage these logistics, they wouldn't have to deal with with the backlash. Well, that's just not doing fiduciary duty for the shareholders.
Edit: And I'm not apologizing for them, but let's be serious and sincere for a moment in our critical thinking and criticisms of why this may have happened. Maybe their whole routing system did go down. Maybe the weather did impact some deliveries. But the stories I'm reading also include a lot of what Double00 is saying, too. Is this really the worst thing that can happen to you during the holidays? If so, count your blessings. Seriously.
