Every business leader knows checking your email can be a huge time-suck. But a recent study by Adobe describes this problem with some pretty surprising numbers. According to its data, the average white collar worker will spend 4.1 hours checking their work email each day. That’s 20.5 hours each week, more than 1,000 hours each year, more than 47,000 hours over a career! Yikes.
