12. Which supervisor's action can invalidate the appraisal instrument?
Answer: B
Monitoring computers to gather information without employees' knowledge can invalidate the appraisal instrument.
This action undermines the integrity of the appraisal process by violating employees' privacy and trust. When supervisors gather performance information without the employees' knowledge, it creates an unfair evaluation environment.
A) Using an informal communication style to deliver the information
This option is incorrect because the communication style does not inherently affect the validity of the appraisal instrument. While formal communication may be preferred in certain contexts, an informal style does not invalidate the appraisal itself unless it leads to misunderstandings or misinterpretations of the evaluation criteria.
B) Monitoring computers to gather information without employees' knowledge
This is the correct option as it directly compromises the ethical standards and transparency required in employee evaluations. Such actions can lead to a lack of trust and may result in legal ramifications, thus invalidating the appraisal instrument.
C) Sharing the data with the employee's colleague
This option is incorrect because sharing appraisal data, while potentially inappropriate, does not directly invalidate the appraisal instrument itself. The validity is more about how the data was collected rather than how it is shared after being gathered.
D) Lacking the skills to give good feedback
This choice is incorrect as lacking feedback skills does not invalidate the appraisal instrument. While it may affect the quality of the feedback provided, the appraisal itself remains valid as long as the process aligns with established criteria and standards.
Conclusion
Monitoring computers without employees' knowledge is a serious breach of ethical standards that can nullify the appraisal process. Other options, while they may raise concerns regarding communication or feedback quality, do not fundamentally compromise the appraisal's validity as this action does. Thus, option B is definitively the correct answer.
