Federal workers in the Washington area should report to duty as usual Friday morning, the first day without optional leave or teleworking since thunderstorms wreaked havoc on the region one week ago.

But agency supervisors are being encouraged to show flexibility with workers still without power in their homes.

An announcement from the Office of Personnel Management (OPM) on Thursday afternoon said that “employees are expected to report to their worksites or begin telework on time. Normal operating procedures are in effect.”

OPM said the dwindling numbers of homes without power as well as improved road conditions affected the decision to return to normal duty Friday

“We received information today that at least 90 percent of the National Capital Region has had their power restored, which influenced our decision for tomorrow’s open status,” Thomas Richards, OPM’s director of communications, said Thursday evening.

“However, even with the open status, we encourage supervisors to work with employees who continue to be affected by the storm,” he added.

Richards said OPM had no information on the number of employees who made use of the option to take leave or telework over the course of the week.

Richards also noted that there were 60 intersection lights not working in the District on July 4, but by late Thursday, the number was less than five.

Friday is forecast to be another in a series of exceedingly hot days in the region.
