Which of the following is an example of a procedure?

A procedure is a specific method or series of actions taken to accomplish a particular task. In this context, "Onboarding" is indeed an example of a procedure as it details the steps involved in integrating new employees into an organization. This process typically includes orientation sessions, training, and introduction to company policies and culture, providing clear guidelines for both the new employees and the HR staff.

The other options represent broader concepts or policies rather than specific methods or steps. "Anti Discrimination" is a policy aimed at preventing discrimination in the workplace, "Code of Conduct" outlines expected behaviors and ethical standards, while "Equality and Diversity" refers to principles advocating fair treatment and inclusion. These concepts guide behavior and set expectations but do not provide specific procedural steps like onboarding does.
