Which of the following is a ground for discrimination?

Discrimination occurs when individuals are treated unfairly or unjustly based on certain characteristics, rather than their abilities or qualifications. Gender is considered a ground for discrimination because it involves treating someone unfavorably because of their sex. This is a violation of equal opportunity laws and principles that advocate for fair treatment in the workplace and society at large.

The focus on gender as a ground for discrimination highlights the importance society places on protecting individuals from biases that could hinder their employment opportunities or career advancement solely due to their gender. Recognizing gender as a basis for discrimination helps in implementing policies aimed at promoting equality and preventing gender-based discrimination.

In contrast, the other options — work performance, job title, and employment duration — are all related to an individual's qualifications or position rather than inherent characteristics. Discriminating based on these factors does not typically represent a violation of ethical or legal standards related to equality and fair treatment in the workplace.
