Leadership Style: A tool to enhanced productivity. This book examined the extent to which leadership styles of principals in secondary schools correlate with teachers' job performance. The author pointed out that no one leadership style is superior to the other and that the situation at hand determines what style or styles to be employed for maximum productivity. He hopes that by knowing what the situation at hand is by the principal and employing the right style or styles, it does influence teachers' job performance for good. Otherwise, the reverse is the case.
