Many child welfare agencies have experienced high worker turnover in recent years. The cost of such turnover is significant, both in dollars and in human terms. For every worker who leaves, the agency must recruit, hire, and train a replacement at considerable cost. Studies also point to worker turnover as having a negative effect on the children and families being served, disrupting service delivery and delaying the achievement of important service outcomes.
