In the 1930s, the popular radio program The Shadow featured an invisible avenger who possessed “the mysterious power to cloud men’s minds, so they could not see him.” (He supposedly picked up this power in East Asia, which must have seemed mysterious in an era before Kung Pao Chicken was widely available.)
Eighty years later, “shadowing” has a different meaning. An unpaid trainee follows around a more experienced employee as a way to learn the business. Few trainees have mastered the power of invisibility [Note: only the best ones have, and they’re hard to find … ba-dum-bum], and often the nature of being a trainee involves getting in the way of the real work.
Scott Axel was a trainee who shadowed his father at an automobile wholesaler in Florida. He had no expectation of pay, and the business said it would not hire him. As a favor to his dad, the business let him learn the business by shadowing his dad.
