A new study shows that while many of us can't do our jobs without email, it can stress us out — and that personality differences affect how we use email and what we find stressful. The results showed that those of us who focus on the big picture are more likely to check our emails on vacation, on weekends, and before and after work than those who focus more on the facts. Unfortunately, sending emails outside of working hours is stressful, as does the amount of emails we send and receive. Managers, regardless of personality type, are more likely to feel they are wasting time on email and find it overwhelming and stressful. The data was collected through an online survey of 368 people, who had already completed a kind of personality questionnaire.
