This is a reasonable place to be at work on Thanksgiving. Walmart and Sears are not.
As a society, there are certain people we need to work on Thanksgiving. Whether it's a car accident, a heart attack, or a burn from a roasting turkey, we need doctors and nurses and other hospital staff to be on the job even though it's a holiday. We need fire fighters, police, and a few others.
We don't need Radio Shack or Walmart salespeople to be at work, but they are. So if you're sitting down to Thanksgiving dinner with family or friends, or for that matter if you're going to the movies or staying home alone and staging a Buffy the Vampire Slayer marathon, spare a thought for people who are on the job today. Spare a thought also for people who can't afford the big meal with turkey and all the trimmings—and remember that many of the very same people working at Walmart and Target fall into that category, or barely escape it.
If you're thinking about sauntering out to do a little shopping after you eat, remember that workers had to be there well before the stores opened. Remember that many of them don't want to be there, as the petitions and protests we see each year attest. And remember that common reasons to be glad to work the holiday include not getting paid holidays off of work, and being so underpaid that extra pay for working a holiday could mean the difference between paying the bills and not paying the bills.
Whatever Thanksgiving means to you, it shouldn't be a symbol of the race to the bottom.
