Embracing Creative Nonconformists and Promoting Them May Require Leaders' High Control Appraisals

Journal of Organizational Behavior, EarlyView.
ABSTRACT Promoting creative employees is essential to innovation and organizational success. However, leaders do not always embrace the nonconformist nature of creative behaviors. This study examines how leaders' control appraisals—a personal orientation reflecting their belief in their own ability to control situations—influence their receptiveness ...
