Why didn't Hospice social worker help client?

Social worker has seen the way the 1 st family member took care of the client. No problems .No complaints. Patient Happy. 2 and family member there now Health, Attitude, Appetite have gone down hill very drastically in only a week. Social worker is bias on the wrong craregiver. SW is allowing #2 family to do this even though the SW knows its wrong. Allowing patient to die without having his favorite family member there. Its tearing him apart
