Children that grow up without adequate parental care are often faced with numerous crisis situations that may cause separating them from their biological families and placing them for care in particular facilities or to other people, especially when their safety is at high risk. This type of care is called alternative care for children. They are oftentimes accomodated in children's homes, which are today faced with numerous critics. Working in children's home may oftten be challenging and difficult durring usual conditions, but when dealing with large-scale crisis situations, such as coronavirus pandemic and/or earthquakes, people are left questioning how does such institutional care manage to function and how does it affect on some already traumatized and vulnerable children. This thesis will make an effort to present opinions of social workers who work in children's homes, about the impact that pandemic and/or earthquakes made on children living in children's homes across Croatia. How is social work in children's home adjusting, how the needs of children are met, how are risk & protection factors and children's resistance in large-scale crisis observed, also, how they estimate indicators of stress and/or trauma in children, as well in themselves is going to be researched and introduced from social workers point of view. This study wants to primarily put focus on safety of children, and therefore recognize negative aspects of institutionalization, whose far-reaching consequences are seen from the impact of pandemic and/or earthquakes. Secondary, the focus is on necessary changes in the social welfare system, that would strive in reducing the number of children in children's homes, and increasing the number of non-institutional social services for children without adequate parental care.
