There are different styles of leadership. Each of them depend heavily on the work profile of the team that is being integrated (there are very competitive teams and others that are less so). Also, the leadership style must adapt to the characteristics of each member (taking into account the motivation and competence of each). But if we want to know what leadership style works best according to the level of discipline to be applied, the ideal is that business leaders can combine more than one style. The key is that each leader is strict with the outcome of the research but flexible with the forms used by the employee to address this outcome.
No single leadership style is better or works for everyone in all situations that arise. Each style has its strengths and weaknesses. The directive approach, to cite one example, is important in times of crisis or when a leader must lead a group that is performing poorly, but if exceeded in use, it can affect the initiative and innovation. Moreover, the affiliate approach is appropriate when employees go through some personal crisis or great personal stress, but it is much more effective when used in conjunction with participatory and visionary styles. Finally the exemplary style can give short term results but ends eroding employee morale. In short, every leader should use each of these styles and use them in the most appropriate times.
