Today we have a legal holiday (as opposed to an illegal holiday?) because of the toil and sacrifice of many people in the past. They suffered to bring us relief from endless hours of drudgery.
We've also got the 40-hour work week and the abolishing of child labor due to the efforts of people working for basic, decent human rights against big businesses.
Remember them in your definition of "heroes"-- those who put out extraordinary effort and sometimes put themselves in harm's way to give us all a better life.
