Thanks to 24/7 connectivity, the boundaries between work and life are eroding, several studies have found. A survey from EY, a global assurance, tax, and advisory services organization, found that 64% of U.S. workers report they’re working two to four hours more a week, and one-third (36%) are on the job an extra five hours or more. No wonder satisfaction with work-life balance is sliding downward as well. Glassdoor’s most recent survey of employee feedback from about 60,000 company reviews revealed a drop in ratings from 3.5 (out of a possible 5) in 2009 to 3.2 this year.
