At the request of children rights and care quality, all types of residential care for youth are committed to creating an image of ＂homely＂ family. Agent's staffs, social workers and direct-care workers, are expected to play roles as parents and partners and to respond consistently to children's needs in daily care. However, the disparity between these two teams workers in term of job design, wage level, responsibility and prestige, has caused a serious 'family fuse' and make it difficult to corporate and function well. Designed as a critical ethnography study, participatory observation and various types of conversational interviews are used as data collecting strategies in this study. Service users and agency staffs are invited to participate and to report their native point of view in a natural setting. This article aims to provide precise and thick descriptions on conflicts and disputes between social workers and direct-care workers, as well as to deepen our understandings about everyday lives and interaction at children's residential home. Using 'activities', 'power', and 'identity' as three analytical framework, different scenarios and dialogue are presented as examples to demonstrate imbalance and unequal plight that both teams have endured. With the privileges of higher pay, feasible and friendly working time, comfortable environment and a 'good guy' face, social workers are expected to prove themselves with professional and effective performance. However, it seems impossible to persuade managerial and external evaluators, nor direct-care workers, to approve social work profession. Because social workers spend too much time on indirect service instead of working with youths directly, social work expertise has been hollowing out gradually. To redesign job, to restore trust, and to possess one's own identity seems to be urgent and important strategies for social work development.
