Unit 5 Discussion No unread replies.No replies. In 2-3 paragraphs, respond to the following. Your initial post should be substantive and be supported by course concepts. Your initial post is due by Wednesday to allow other students to respond. Consider a leader you admire. After reading the unit chapters explain this person's leadership style and how he/she embraces diversity.
