Current leadership style includes promotion based on seniority, insufficient training, employees have little to no involvement in the decision making process and results based management style resistivity to adaptation and change.

I want to suggest changes that include a combination of democratic and participative leadership, promotion based on skill and expertise and and encouraging teamwork and creativity

to implement these changes I plan to organize at the organizational level departmentalize cluster jobs, collaboration as a team, use of employee feedback to generate positive change within policies and offer various training and skill assessment workshops

What could I say in a presentation to convey the changes I am making and why they will help?
