What's your preferred style of leadership?

Collaborative: considering everyone's opinion (see Peter F. Drucker, e.g. or https://medium.com/@ChangeistheonlyConstant/effective-decision-making-lessons-from-peter-drucker-9abc9cd9672dor his book "The Effective Executive")

Every type of leadership is needed in different phases of the company growth, sustenance and decline

As others stated. Situational Leadership trumps the one-style-fits-all approaches.  Moreover, Situational Leadership needs to recognize the the types of goals and business model for the organization.  While most professionals respond best to authoritative or coaching styles, some business functions are designed around discrete objectives where an autocratic approach simply works best.

Situational leadership. As the name points out, according to the situation with someone or the timing itself I’ll change my leadership style. It could be that someone needs micromanagement or that requires coaching.

Difficult to say that one style applies. Have you heard of Situational Leadership? A leader needs to align with the expectations of his team. A new joiner needs a directive style, while a seasoned professional will be extremely annoyed with a directive style. Similarly, a new joiner might be lost with a coaching style. So the mark of a good leader is the one who can anticipate the needs of his people and practice adaptive and situational leadership. I have a team of experts, so I do have a great opportunity to expand them and eventually kill my own job. Therefore I practice “coaching style” i.e. supportive leadership.
