Psychologists find that experiencing rudeness at work from customers and colleagues increases absenteeism and decreases sales performance. That doesn’t mean that managers can’t step in and improve things. Psychologist Michael Leiter says:
“A big part of the intervention is just to get people to talk about their relationships rather than just getting ticked off with people and complaining to their friends… That’s part of your professional responsibility: to maintain good working relationships just like you maintain equipment and report breakdowns… You don’t have to wait until people get cynical or quit in disgust; it’s something management can do something about.”
