The correct answer is A. All are examples of workplace discrimination
Step-by-step explanation:
Discrimination refers to practices against an individual or group of people based on gender, origin, race, likes or personal prejudices. In workplace discrimination occurs as the employer or other workers treat another person unfairly. This includes excluding the person in a meeting or similar context, firing her or him for unfair reasons or based on prejudices, giving the person more or less work due to age, removing the person from a position (demounting), denying benefits to certain employees, paying different salaries for the same position, among others.
Thus, all are examples of workplace discrimination (demoting, firing or reducing pay or hours) although there are many other practices in which people can be treated unfairly based on gender, origin, race, and other elements that do not affect their performance at work.
