Structural unemployment

Explanation:

Structural unemployment occurs when the skills required by employers are different from those possessed by the workers (there is a mismatch). This usually occurs as a result of technological change where automation replaces human labor in some manufacturing process.

In this instance automobile workers became unemployed because robots took over some production processes.

Now jobs for computer programmers are the ones in demand, because the workers do not have this skill they are unemployed.
