What are the problems of human relations in business?

Although some analysts can try to reduce business issues to a matter of numbers, much of the success of businesses depends on human relations.
First, human relationships are central to human resource management. Hiring and retaining good employees isn't just a matter of salary and benefit packages. Employees who dislike the human side of their work environment will search for other jobs and might perform below peak efficiency in their current roles. Effective management practices also take into account fostering productive collegial relationships.
Next, customer relationships are ultimately human relationships. Everything from brand loyalty to repeat business depends on establishing good relationships with customers. The ubiquity of social media tends to amplify the effects of good or bad relationships with customers, as a single rude or unpleasant interaction can end up going viral and having a negative effect on your company's reputation. 
To foster good human relationships and avoid problems, companies should train employees in issues such as cross-cultural communications and sensitivity to different cultures to avoid inadvertently offending people.
