U.S. lawyers are still spending too little of their workday on billable hours, a year after an eye-opening report found lawyers devoted only 29 percent — 2.3 hours — of each eight-hour workday to billable hours.

This year’s Legal Trends Report, prepared by Clio, a Canadian company that provides cloud-based practice management for firms, found that the average utilization rate improved only incrementally to 30 percent, which is 2.4 hours of billable hours each workday.
