It is very different from Christmas, Thanksgiving, or other well-known holidays. It is called Take Our Daughters and Sons to Work Day. This holiday is meant to be educational as well as fun. The idea is simple, and the name says it all. It is a day for working parents to show their kids what they do all day. Although this holiday doesn't seem very complex , it has meaningful purposes.
