Volunteering happens when an individual or a group offers their time or labour for free. It is an act of community service that doesn’t require prior training or experience. Many volunteers serve on an as-needed basis, such as in response to a natural disaster. Other volunteers could be specifically trained in the areas they work, such as medicine, education, or emergency rescue.

Volunteering has many benefits, and following are some examples:
