Davis (1998) conducted an examination of California school superintendents, revealing that the primary reason most superintendents and principals were fired was because they had not developed good interpersonal communication skills or had failed to employ their skills at work with their subordinates. Bulach, Boothe, and Pickett (1998), studied 375 teachers and determined fourteen specific clusters of school principals' errors or disruptive behaviors. The researchers found that principals' errors in interpersonal relationships and communication were the ones mentioned most often by teachers in the study. Such subsets of leadership mistakes often stated by teachers were trust deficiencies and indifferent and insensitive attitudes and the most mentioned one was lack of listening skills on the part of educational leaders. Furthermore, in their literature study, Bulach et al. (1998) found that nothing substantial was found in the school curricula of the three different American states studied regarding training educational leaders in relationship building. The authors' clear implication from their statement is that, if the opposite were true, this would have a major positive effect on the overall functioning of schools, from top to bottom in the supply chain.
