When I first encountered the term “participative
leadership” I was kind of puzzled. What kind of a leader cannot or does not participate? Is it possible to lead at all without participation?

The search offered some answers on the topic, nevertheless I was amazed that most authors won’t distinguish two important but different roles, managers and leaders: “… as it is within the managers' whim to give or deny control…” or “…in the participative
leadership style, effective managers solicit input from subordinates …”. Participative leadership pertains to leaders, doesn't it? (see:
Leader vs. manager).
Another statement “a participative leader, rather than taking autocratic decisions, seeks to involve other people in the process” was pretty much familiar - the same definition was ascribed to charismatic leadership (
Charismatic Leadership).
Among many more publications about participative leadership I came across the definition “… the leader turns to the team for input, ideas and observations instead of making all decision on his or her own.” Well, can a leader really lead without inputs from his team? I sincerely doubt it.
