If workers at the school canteen cannot sell during the holidays, this is example of

Step 1: Analyze the question The question describes canteen workers who cannot sell during school holidays. The key point is that the lack of work is tied to a particular time of the year (the holiday period), and it returns regularly.

Step 2: Explain the concept Types of unemployment:

• Structural unemployment: caused by changes in the structure of the economy, such as new technology or a decline of an industry, so workers' skills no longer match available jobs.
• Frictional unemployment: short-term unemployment while workers move between jobs or search for a better one.
• Seasonal unemployment: caused by regular, predictable changes in demand during certain seasons or periods of the year. Examples include farm workers in the off-season, ice cream sellers in the cold season, and school canteen staff during holidays.
• Residual unemployment: affects people who cannot work because of physical or mental disabilities or similar limitations.

Step 3: Apply to the question The canteen's business depends on students being in school. When school is on holiday, there are no customers, so the workers are idle. This happens every year at predictable times, and the workers go back to work when school resumes. This fits seasonal unemployment exactly.

• A is wrong because the economy's structure has not changed.
• B is wrong because the workers are not between jobs or searching for new ones.
• D is wrong because it is not about disability or personal limitations.

Step 4: Answer The correct option is C. seasonal unemployment.

Exam tip: Look for time clues such as "holidays", "off-season", "harvest period" or "rainy season". When unemployment is linked to a time of year and repeats regularly, think seasonal.
