Explanation:

Human relations are defined as the study of group behavior for the purpose of improving interpersonal relationships as among employees. Human relations is an important part to our career success. It is defined as relations with or between people, particularly in a workplace setting. Because a company depends on good human relations through its organizational structure, developing these skills is important.
Technology has greatly impacted human relations because so much of our communication occurs without the advantage of seeing body language. This can result in miscommunications. Many workers telecommute to work. There are advantages and disadvantages, a more notable disadvantage being the lack of human, face-to-face contact.
There was an evolution in human relations study. In the classical school of management, the focus was on efficiency and not on human relations.
Employees began to unionize in the 1920s due to lack of positive human relations, and therefore the behavioral school of management was created. During this time period, researchers began to focus on the human relations aspect of the workplace. One of the major theories developed was the Hawthorne effect, which determined that workers were more productive when they were being watched and cared about by researchers.
