Labor Day celebrates the workers who have made America what it is today. And all throughout the country, our public schools are full of some of the hardest-working people I have ever met.

They invest countless hours in our kids, incliuding long days, weekends, even summer vacations. Most educators are driven by one mission: Making sure students get access to the education and life skills they need to succeed.
