Frictional unemployment comes from voluntary transitions within an economy and is naturally occurring, even in stable/growing economies. It’s healthy for workers to choose when to leave their jobs in search of new (and often better) ones or when people enter the labor market in search of work. In this scene from The Office, Michael Scott quits after being annoyed by how his company has treated him over the past 15 years. Michael is comfortable quitting, even after it seems that he will get what he wants because he believes there is more out there for him.
Thanks to Allison Anthony for the scene suggestion!
