Elton Mayo's human relations theory is a theory that states that employee satisfaction and productivity can be increased by improving the working conditions of workers. The theory is based on the idea that employees are more productive when they feel valued, respected and appreciated by their employers.

Mayo's theory focuses on the role of managers in creating a positive work environment for employees. He believed that managers should be involved in the lives of their workers outside of the workplace and make sure they feel valued and appreciated by their employers.

Mayo also believed that good leaders should communicate with their employees regularly and show them how important they are to their company's success. He thought that if managers made an effort to understand what motivated each individual employee then it would be easier for them to get things done efficiently at work without causing any problems between coworkers or supervisors/managers who may not have been communicating properly before hand about certain issues affecting everyone else around them (including themselves).

Elton Mayo was a psychologist who developed a human relations theory in the 1920s. This theory focused on how workers are motivated, and it helped shape the way that companies structure their workplaces.

Mayo believed that humans are inherently social beings, and they thrive when they're able to connect with one another. He also believed that workers could be motivated by being given responsibility over their work, rather than strictly following orders.

He used this theory to develop ways to make workers more productive by giving them more freedom at work. For example, he encouraged managers and other employees to treat each other as equals and to treat all workers with respect.

The four main types of human relations are:

1. Personal relationship: In a personal relationship, you have a one-on-one connection with someone. You can talk to them about your feelings and experiences, but they may not be able to relate to what you're saying. A personal relationship can be between two friends or family members, but it's not usually between employees and their boss.

2. Interpersonal relationship: An interpersonal relationship is a connection between two people who have a shared goal or interest. It could be between coworkers who are part of the same team or instructors working together to create curriculum for an online course.

3. Group relationship: A group relationship is when multiple people come together to accomplish something or share a common interest or goal. For example, if your company has an employee appreciation day, everyone will come together as a group to celebrate each other's achievements throughout the year.

4. Organizational relationship: An organizational relationship is when many individuals work together towards a common goal or purpose within an organization (like an office).
