Solution
Option 1 -> Discipline refers to obedience, respect for authority, and following organizational rules. Bias in conflict resolution doesn't directly violate this principle.
Option 2 -> Order means having the right resources in the right place and the right person in the right job. This principle is about organizational arrangement, not fair treatment.
Option 3 -> Equity requires managers to be fair, just, and impartial to all employees without discrimination. Showing bias towards female employees violates equal and fair treatment for all.
Option 4 -> Unity of Direction means activities with similar objectives should be under one manager with one plan. This relates to organizational structure, not impartial treatment.
Hence, Option 3: Equity -> When a manager shows bias towards female employees in conflict resolution, they are not treating all employees fairly and equally, which directly violates the principle of equity that demands justice and impartiality in dealing with all employees regardless of gender or other factors -> correct
