Re “How iPhones Ruin Your Posture and Your Mood,” by Amy Cuddy (Sunday Review, Dec. 13):
Not only does drooping your head over an iPhone ruin your posture and your mood, as Ms. Cuddy points out, but it also has a detrimental effect on your co-workers, who are forced to watch a fellow worker at play, browsing the Internet, reading email or playing games. Hard-working employees who follow the rules no doubt will become demoralized.
When a supervisor notices a cellphone abuser, unless that employee is on break time, he should be called out on his offense.
