In his farewell address, President Harry Truman said “the greatest part of the president’s job is to make decisions — big ones and small ones, dozens of them almost every day. No one else can do the deciding for him. That’s his job.”

But what was the job of “Give ‘em Hell, Harry” before he became president? How did he and his fellow future presidents pay the bills before they moved into the White House?

This Labor Day, as we honor America’s working men and women, take the quiz below and test your knowledge of the jobs some presidents held before sitting down at the Resolute Desk.

Thomas Dewey narrowly lost to Harry S. Truman in 1948 after eking out the nomination over Ohio Sen. Robert Taft in the last brokered Republican convention. Some are predicting another brokered convention this year if the Republican contest remains close. The famous Chicago Tribune headline declaring Dewey the winner is an unforgettable image from that election year.
