Social workers often work in close relationship with various councils to provide adequate living space for homeless people in the form of sheltered housing. Housing & Environment is the field within social work concerned with placing children at appropriate foster care homes, supporting families, and providing adequate housing to the elderly, and ensuring sheltered housing for the vulnerable. Within this field social workers can also be employed by the government bodies to investigate issues affecting communities and may need to report on possible solutions. The housing officer is normally employed by the councils or social work authorities.
