"Loud phone conversations, [use of] speaker phones and constant complaints about workload top the list of our co-workers' most annoying work habits," reports the Washington Post. Among other habits that anger fellow workers are "cliques among co-workers, arriving late to work, talking to oneself, talking to co-workers over cubicle walls, bad hygiene and loud eating." Such bad habits also damage worker productivity. Most of those who responded to researcher's questions admitted, however, that they had never confronted those who irritate them. "And for good reason," says the newspaper. "They can be just as guilty themselves."
