47. Who of the following is least likely to belong to a union?

a file clerk in the federal government

a semi-skilled laborer in the steel industry

a computer analyst at a high-tech firm

a mechanic in the airline industry

A computer analyst at a high-tech firm.

Explanation:

The need to form a union is realized through the need to protect the interests of the individuals working at the same level in the same profession. A union is effective only when it has a huge number of members actively working. The profession of a computer analyst is rare and usually in demand. Moreover, the chances of a computer analyst's interests getting harmed in a high-tech firm are very low and hence there no need of a union for the SIAD profession.
