Which phrase denotes job functions that are the basis for the existence of the job?

• A. Essential functions
• B. Core duties
• C. Primary tasks
• D. Job responsibilities

Answer: (A)

The key idea here is identifying terms that express what a job must do to exist. Essential functions are the tasks that are truly required for the job to serve its core purpose; without performing these duties, the role wouldn’t have a reason to exist. That’s why this phrase best captures the idea of the job’s indispensable activities. Other terms—like core duties or primary tasks—refer to important activities but aren’t the standard labeled concept for what makes a job exist. Job responsibilities is a broader umbrella that can include nonessential duties as well.
