Instead there is a Senior Associate or an Executive Pastor who is responsible. In that case both the Senior Pastor and Executive Pastor attend the committee. Still the Senior Pastor is who is finally held responsible. Some churches make the horrible mistake of assigning each staff member to one of the SPRC members. Now it is possible for staff to have problems with the Senior Pastor and the problem be discussed with the SPRC member before the Senior Pastor.
Triangulation can occur now in as many times as there are staff members.
And let the Senior Pastor design a method of evaluation and hiring of the staff. If the Senior Pastor is not mature enough to do this, then that is another story and we all know what that is - not put or leave that person in that position. Only the most spiritual leaders of the church should serve on this committee.
