I used to have a photo taken on Christmas Eve in Tempe in the lab at work in the late 90s -- I wish I knew where it is now.
A senior exec dropped by the office to check on a project and found the only two workers in the building -- me and the only other contractor on the project -- sitting side by side working on Xmas Eve. He took our picture from behind us.
Kind of points to the state of labor in America. I'm not sure which is more pathetic -- that we were working or that nobody else cared enough to.
