Many researchers have been pinning workplace stress and overload on email communications. Some have put the blame on the vast number of incoming emails, others say that while the latter might have an influence, it’s heavily mediated by what is perceived to be effective or preferred email communication.Another factor seems to be how much emails interrupt the workflow. Does it sneak in a lot of new and unplanned tasks? Is it constantly calling for attention? Does it demand a lot of going back and forth to figure out what the other party is actually trying to say? Surprisingly, it has been found that that state that those that send more work-related emails during their free time are less stressed. Scholars speculate that it might be because those who already feel strained retrain from any after-hours engagement.
