A volunteer is someone who "works for free" or someone "working of their own free will." People choose to volunteer for many reasons. Some people choose to do this because they want to help, and others hope that they might get jobs if they do their volunteer work with care. Parents often volunteer in their children's classrooms or help raise money for their children's schools. No matter the reasons, becoming a volunteer helps many people feel good about themselves. There is something about 'working for free' that allows people to feel that they are making a positive difference in their community. Employers will often choose to hire someone who has volunteered for them because they have already proven themselves. Whatever the reason, becoming a volunteer will open new doors for you and you can bet that you will feel like you really did make a difference.
