First, of the top ten reasons people are fired, several reasons relate back to lack of human relations skills—for example, the inability to work within a team, personality issues, sexual harassment, and dishonesty. [2] Other reasons, perhaps not directly related to human relations, include absenteeism, poor performance, stealing, political reasons, downsizing, and sabotage. Second, people who are competent team players and have a good work ethic tend to get promoted faster. [3] In fact, according to guru on personal development Brian Tracy, 85 percent of your success in life is determined by social skills and the ability to interact positively and effectively with others. [4] Another reason to develop good relationships with others relates to your own personal happiness. According to psychologist Sydney Jourard, most joy in life comes from happy relationships with other people. [5]
