Final answer:
Participative leadership has major effects on groups or organizations, including increased productivity and motivation, improved hierarchical structure, and reduced employee engagement.
Step-by-step explanation:
Participative leadership has major effects on groups or organizations, including increased productivity and motivation, improved hierarchical structure, and reduced employee engagement. When leaders involve employees in decision making and encourage their input, it can lead to higher productivity and motivation as employees feel valued and engaged. This leadership style also improves the hierarchical structure of the organization by distributing decision-making responsibility and empowering employees. However, reduced employee engagement can occur if employees feel overwhelmed by too much participation or if the leader does not effectively communicate and involve all team members.
