Manual labor refers to work that requires physical effort and is often performed by hand. This type of work can include tasks like construction, farming, or cleaning. People who engage in manual labor typically use their strength and skills to complete jobs that may involve lifting, digging, or operating tools. Many manual labor jobs are essential for society, as they help build and maintain infrastructure, produce food, and provide services. While these jobs can be physically demanding, they also offer a sense of accomplishment and can be rewarding for those who enjoy working with their hands and seeing tangible results from their efforts.
