What should be the basis of fair evaluation in work?

Correct answer: Clear criteria and equal rules

The direct answer is A: fair evaluation must use clear criteria and equal rules. Evaluation means judging a person’s work or performance. To be fair, everyone should know what is being judged, how it will be judged, and what standard applies. Step by step: first, decide measurable criteria; second, communicate them openly; third, apply the same rules to every worker; fourth, base the result on evidence rather than personal liking. Option A is correct because clarity and equality reduce bias and make decisions transparent. Option B, personal preference, is subjective and can favour one person unfairly. Option C, rumour, is unverified information and cannot prove work quality. Option D, hidden rules, prevent people from understanding or challenging the decision. Fair evaluation supports trust, motivation, and workplace justice. Memory cue: fair assessment means same standard, known in advance, based on evidence.
