Today is Labor Day, a day invented to celebrate the workers of our country. For a lot of people, the day is for shopping sales, having cookouts and wetting a boat keel. But for an awful lot of people this Labor Day, it's not a day off.

It's a day of work for police officers.

It's a day of work for fire crews.

It's a day of work for ambulance crews.

It's a day of work for hospital workers - doctors, nurses and orderlies.

It's a day of work for American men and women in harm's way overseas.

It's a day of work for the people who keep our lives safe, who take care of us if we have a problem, and for those who ensure our liberty with their very lives.

Have a wonderful holiday, but take a minute to remember those who have something more important to do.
