People skills are patterns of behavior and behavior interactions, among people; it is an umbrella term for skills under three related set of abilities: personal effectiveness, interaction skills, and intercession skills. This is an area of exploration about how a person behaves and how they are perceived irrespective of their thinking and feeling. It is further elaborated as dynamics between personal ecology (cognitive, affective, physical and spiritual dimensions) and its function with other people's personality styles in numerous environments (life event's, institution's, life challenges...etc). British dictionary definition is "the ability to communicate effectively with people in a friendly way, especially in business" or personal effectiveness skills. In business it is a connection among people in a humane level to achieve productivity.
Portland Business Journal describes people skills as:
- Ability to effectively communicate, understand and empathize.
- Ability to interact with others respectfully and develop productive working relationship to minimize conflict and maximize rapport.
- Ability to build sincerity and trust; moderate behaviors (less impulsive) and enhance agreeableness.
Guidelines relating to what later generations eventually dubbed "people skills" have been recorded from very early times. Five examples of early human guidelines appear in the Bible. 1 Peter 4:8-9 advises: "Above all, maintain constant love for one another, for love covers a multitude of sins. Be hospitable to one another without complaining."; and Solomon's wisdom in Proverbs 15:1 includes: "A soft answer turns away wrath, but a harsh word stirs up anger.", along similar lines in Proverbs 16:21 includes: "The wise of heart is called perceptive, and pleasant speech increases persuasiveness."; 1 Thessalonians 5:14 dictates: "And we urge you, beloved, to discourage the idlers, encourage the fainthearted, help the weak, be patient with all of them."; Titus 3:2 advises: " To speak evil of no one, to avoid quarreling, to be gentle, and to show every courtesy to everyone."; and in Galatians 6:2 encourages: "Bear one another’s burdens, and in this way you will fulfill the law of Christ." 
Human-relations studies became a movement in the 1920s, as companies became more interested in the "soft skills" and interpersonal skills of employees. In organizations, improving people skills became a specialized role of the corporate trainer. By the mid-1930s, Dale Carnegie popularized people skills in How to Win Friends and Influence People and How to Stop Worrying and Start Living world-wide.
In the 1960s, US schools introduced people-skills topics and methods—often as a way to promote better self-esteem, communication and social interaction. These encompassed psychologist Thomas Gordon's "Effectiveness Training" variations as well as many other training programs. (By the 1980s, "traditional education" and a "back-to-basics" three-Rs emphasis largely pushed these programs aside, with notable exceptions.)
By 1974 the actual term "people skills" had come into use.
Business, labor and government authorities agree that wide-ranging people skills are necessary for 20th-century work success in the SCANS report. Skills like customer service, building effective relationships, and team work are among the abilities most requested by employers in job postings. Lacking of these skills are considered serious psychological handicap. Constructive leadership based companies engage in helping individuals to grow, and through that growth employees take more responsibility and discharge it effectively. This in-turn will enhance basic attitude of the individual; and that will reflect the general level of performance in workplace. Lawrence A. Appley of American Management Association, reflected on these training as a responsibility "increase the knowledge, sharpen and add to the skills, improve the habits, and change the attitudes of many of those for whose development we are responsible." Lack of people skills among upper echelons (top management) can result into bullying and/or harassment and it is not uncommon in the modern workplace due to changing values. The causes that are most identified with the situation is lack of necessary motivation, communication, influencing skills and empathy gap among upper echelons (Gilbert and Thompson, 2002). Training company staff in people skills and interpersonal skills increases the morale and dignity at work (Best, 2010). Employers that do not take steps to prevent harassment can face major costs in decreased productivity, low morale, increased absenteeism and health care costs, and potential legal expenses.
The Collaborative for Academic Social and Emotional Learning (CASEL) has identified 22 programs in the US that are especially comprehensive in social-emotional learning coverage and effective in documented impacts. UNESCO research found that young people who develop speaking/listening skills and getting to know others without WIIFM attitude have improved self-awareness, social-emotional adjustment and classroom behavior; self-destructive and violent behavior also were decreased. People skills is also important for teachers for effective classroom management. It is identified that 50 percent of classroom success lies in effective interpersonal relationship and the rest 50 percent with academic skills.
