Which group consists of clerical workers providing support to professional staff in the civil service?

The correct answer is clerical workers, as this term specifically refers to individuals who manage various administrative tasks to assist professional staff within organizations, including those in the civil service. Clerical workers are responsible for duties such as data entry, filing, scheduling, and general office management, which are essential in ensuring that the organization operates smoothly.

Understanding the distinction, administrative workers typically encompasses a broader category, which can include a range of roles beyond just clerical functions. Executive assistants usually have specialized responsibilities that involve higher-level tasks and direct support to executives, rather than the general clerical duties associated with the role of clerical workers. Support personnel can include a wide variety of roles that extend beyond clerical functions, such as maintenance or IT support, making this term less specific than clerical workers. Therefore, the most accurate choice for the group that focuses on providing clerical support is indeed clerical workers.
