Duncan, the main character in the movie, The Way, Way Back, is an example of someone who wouldn’t be considered unemployed, even though he does not initially have a job. To be officially classified as unemployed, an individual from the labor force must not be currently working but must be available to work and actively looking for work within the last 4 weeks.
Not only is Duncan only 14 years old—making him too young to be a member of the working-age population—but he also is not looking for a job. In this scene, he is spontaneously offered a job at a water park by a new acquaintance. For classification purposes, he was not part of the labor force and then switched to employed.
