A new study shows that while many of us cannot do our job 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 with a big picture focus are more likely to check our emails on holiday, at the weekend and before and after work than our more matter of fact counterparts. Unfortunately, sending emails outside of work hours leads to stress, as does the amount of emails we send and receive. Managers, regardless of personality type, are more likely to feel that they waste time on email and to find it overwhelming and stressful.
