In this example there are two options that are correct. The first one is “unemployed” as it is a broad term to describe a person that is without a job. The second one is “structurally unemployed” as it is used to refer to someone that lost or cannot find a job because his/her skills are no longer needed. In the scenario given, Job was fired because his technical skills were replaced by technology. Structural unemployment occurs, among other factors, when economies look for new kind of skills whereas old skills are outdated or no longer useful.
Frictionally unemployed refers to workers that are voluntarily between jobs. Cyclical unemployed refers to the ups and downs of the economy. When an economy is in recession, cyclical unemployment is common since there might be jobs lost.
