Starting from the top in terms of, well you have to start somewhere . . .  an autocratic leader will often be strident and outspoken with a vision of themselves as the smartest guy on the block by a mile & the rest.  They take no prisoners and generally are not open to discussions or negotiations with colleagues or team members.  Then there are the leaders who show how authoritative they are, they do delegate but will expect top notch results from these discussions.

The democratic leader on the other hand will happily spread the duties and the blame if things go slightly awry from time to time.  Inbetween this selection comes the laissez-faire approach which means the leader has an attitude of trust and reliance on their employee.  They stay a little distant and are not in everyday control in that irritating micro-managing way that puts colleagues and staff in a position to get on in the company.  A good example here is always known for a hands off attitude.  Trust is placed in managers to perform according to their abilities and known experience.  On one hand laissez-faire style of management encourages creativity, good morale, flexibility and development of leadership skills.  However having said that, it can often lead to a lack of direction with sometimes chaotic lack of accountability and risk of exploitation.
