Which of the following is NOT a problem associated with having immediate supervisors conduct employee appraisals?

The choice indicating "Justifying pay increases and promotions" is not considered a problem associated with having immediate supervisors conduct employee appraisals because immediate supervisors are typically in a position to understand their team's performance directly. They observe day-to-day work and can evaluate employees based on that firsthand experience, making it easier for them to justify decisions related to pay raises and promotions. Their closer involvement with employees allows them to provide valid reasons for such decisions, which usually aligns well with the appraisal process.

In contrast, the other options highlight inherent challenges in this appraisal approach. Focusing on one aspect of performance indicates that immediate supervisors may tend to concentrate on specific behaviors or results rather than evaluating an employee comprehensively. Geographical separation can be a problem if supervisors do not have regular or in-person interaction with employees, leading to assessments that may not fully capture an employee's contribution or potential. Technical knowledge disparities refer to situations where a supervisor may lack the specialized knowledge to accurately assess technical roles, which can impact the appraisal's effectiveness and fairness.
