What principle states that all employees should be treated fairly and justly based on ability?

The principle that states all employees should be treated fairly and justly based on ability is Employment Equity. This concept emphasizes the importance of providing equal opportunities in the workplace and ensuring that factors such as race, gender, age, or disability do not impede an employee's chances for advancement or fair treatment.

Employment Equity initiatives aim to identify and eliminate barriers that certain groups may face, thus promoting a workforce where everyone has a fair shot at success based specifically on their skills and contributions. This principle is integral in creating an inclusive work environment where diversity of talent is recognized and valued.

While meritocracy, diversity, and inclusion are related concepts, they focus on slightly different aspects. Meritocracy emphasizes rewarding individuals based on their talent and performance rather than other subjective factors. Diversity refers to the presence and representation of various demographic groups within the workplace, while inclusion focuses on creating an environment where all employees feel welcome and their contributions are valued. Employment equity grounds these principles in the framework of fairness and justice in treatment based on ability.
