Labor Day beckons, dear reader. And all across the country this weekend, plenty of Americans will be busy indulging in their one last hurrah before the summer officially ends.

But there’s a lot more to Labor Day than long weekends and mattress sales, of course. Are you a worker? Well, the labor movement was thinking of you when it founded this holiday in the 19th century to honor (and protest) sweat and toil and 12-hour days. In 1894, President Grover Cleveland made it legit, declaring the first Monday of September a federal holiday.

Aren’t you glad everything is all better now?

This Labor Day, we at The New Food Economy will be thinking of the workers who produce, pick, process, pack, and plate our food—so many of whom are invisible to eaters. In their honor, we’re sharing their stories. Welcome to the secret life of the supply chain.
