Frictional Unemployment

It results from the actual turnover in the labor market and the time taken to get a new job.

This process is termed frictionally unemployed.

Structural Unemployment

Originates from a lack for demand for a specific class of worker due to the worker lacking the appropriate skills needed by the employee as this can cause the worker to lose the job. Another example is sourcing for a reduced cost of labour abroad.
