The "Blue Line" Children's Crisis Foundation has been operating a crisis line for thirty-one years for young people aged 10-24 as well as concerned adults and professionals. They do this with lay volunteers who provide assistance via phone, email, and chat 24 hours a day. This case study attempts to describe their activities and their way to achieve a minimum 2-year volunteer commitment to provide high-quality service in a highly sensitive area to a highly sensitive age group. It describes the mission of the organization, its main values, the peculiarities of operation, the results achieved and the challenges they have to face in the past three decades. The methodology used was the following: a structured interview was conducted with the professional leader of the organization, a group interview with the chairman of the board of trustees and the managing director, as well as eight volunteers and a few members of KVITT, the youth advisory board. The posts and news on the organization's website, relevant materials recorded by staff and articles published in the electronic press were reviewed. In addition, this researcher participated in the 30th anniversary conference and an online workshop on the topic of helpful discussion. Perhaps the greatest achievement of the "Blue Line" Child Crisis Foundation is that it is able to provide a safe space for callers aged 10-24 and concerned adults and professionals, using the methodology of helpful conversation. In 2023, about twenty thousand calls were answered, and in justified cases, specific assistance was provided, such as calling an ambulance, arranging medical or psychiatric care. Volunteer respondents are selected carfully, and they receive thorough training. They do not apply the methodology only during conversations with callers, but they also take it with them to other areas of life, so the impact of the organization is magnified. The impact of the organization is also enhanced by the fact that through in-person and online courses, the opportunities for helping conversation and related methods are spread among teachers, child protection, and health-care professionals.
