Unequal payment for work of equal value challenges which principle?

Correct answer: Fair remuneration

The direct answer is A: unequal payment for work of equal value challenges fair remuneration. Fair remuneration means that people should receive just and non-discriminatory payment for work requiring equal value, effort, skill or responsibility. If two people perform work of equal value but one receives less because of an unfair basis, the principle of fairness is violated. A is correct because it names the payment principle involved. B, workplace decoration, concerns the physical appearance of a workplace and has no necessary connection with wages. C, timetable writing, concerns scheduling, not justice in payment. D, personal interest, means liking a type of work and does not decide whether payment is fair. The exam link is simple: equal value of work should lead to equal and fair remuneration, not arbitrary unequal wages. Remember: equal work value, fair pay.
