Final answer:
To assess work center personnel's performance fairly and effectively, focus should be on job competence and attitude, while also considering educational background for job-specific knowledge.
Step-by-step explanation:
When assessing your work center personnel's performance, it is essential to consider characteristics that accurately reflect their work capabilities and contributions. The most appropriate characteristics to consider are C. Job Competence and Attitude. This encompasses their abilities, skills, work ethic, and how they interact with colleagues and handle responsibilities. Attributes such as educational background may also be considered to some extent to gauge specialized knowledge or qualifications that may be necessary for job performance. However, non-performance-based factors such as age, gender, and marital status are not professional measures of job performance and can lead to discrimination. Instead, focusing on job-related performance metrics and behaviors ensures a fair and effective evaluation.
