Accordingly, this is the first time in history that Google published a Labor Day doodle for American industry workers. The artwork depicts men and women performing industrial trade work.

Clicking the doodle leads to a search for "Labor Day."

"I don't think in Google's history, at least that I can remember, has Google ever posted a Doodle, a Google logo, for Labor Day. They have posted small American flags but nothing more. Even dating back to 2004 and 2005, Google didn't post a Labor Day logo," said Barry Schwartz in a Search Engine Roundtable forum.

"That all changed today with this Doodle. Google didn't comment or add any details around who made the Doodle, but it is indeed live. Which to me was a bit of a shock," he pointed out.

The U.S. Department of Labor said Labor Day, the first Monday in September, is a creation of the labor movement and is dedicated to the social and economic achievements of American workers.

It constitutes a yearly national tribute to the contributions workers have made to the strength, prosperity, and well-being of our country.

"So while you are enjoying this day off from work, take a moment to reflect on those workers who fought for many of the employment benefits many of us take for granted," said Steven Musil of CNET.

The U.S. Department of Labor said Labor Day was originally celebrated in New York City on Tuesday, September 5, 1882, but the first state law making it an official holiday wasn't passed until five years later in Oregon.

By 1894, more than 30 states had made it a holiday, including the District of Columbia.
