Researchers at the university of michigan found that the most effective supervisors were those who established high performance goals and displayed supportive behavior toward subordinates, which are referred to as leaders.

They are called employee-centred leaders.

Explanation:

Leadership is an essential aspect for organizations; the company will always look for leaders who can motivate a group of people to meet the company's objectives. If the person feels motivated by their leader, this will help the performance to be better.

There are different types of leadership; the task-centric leader, the authoritarian leader, the employee-centered leader, among others.

The employee-centered leader cares about his collaborators. He/she is a democratic leader, and delegates the tasks with the members of his group listens to the ideas of his employees and focuses on the interpersonal relationships in the group being well, so that does not interfere in the work environment.

Employee-centric leaders generally help the employee feel satisfied at work, thereby improving their performance. For example, in the case of the University of Michigan research, it was found that employee-centered leaders were the ones who presented the best performance in their jobs.
