This month, 500,000 hopeful substitute teachers are queuing up for work in Los Angeles, New York, Chicago, and countless small-town schools across the nation. I know from first-hand experience that the extra income and flexibility are big draws, especially if one is unemployed.
But I also know that the job can be demanding, low paying, and conducted without supervision or assistance. Who, I wondered, could do this work coolly and expertly and be willing to accept per diems that start at $45 and average $105?
The answers — from the United States, the UK, and Japan — may surprise you.
