SEASONAL UNEMPLOYMENT: Unemployment is caused by relatively regular and predictable declines in particular industries or occupations over the course of a year, often corresponding with the seasons. Unlike cyclical unemployment, that could occur at any time, seasonal unemployment is an essential part of many jobs. For example, your regular, run-of-the-mill, department store Santa Clause can count on 11 months of unemployment each year. Seasonal unemployment is one of four unemployment sources. The other three are cyclical unemployment, frictional unemployment, and structural unemployment.
