Help-line callers are individuals who provide assistance to people in need of help over the phone. They are usually employed by organizations such as charities, government agencies, and private companies. They provide support to people who are facing difficult situations, such as mental health issues, financial problems, or relationship difficulties. Help-line callers are trained to listen to callers, assess their needs, and provide advice and guidance. They also provide referrals to other services and resources that may be able to help.
