Fed Offices Closed on Monday

Non-emergency employees (including employees on pre-approved paid leave) will be granted excused absence (administrative leave) for the number of hours they were scheduled to work unless they are:

• required to telework,
• on official travel outside of the Washington, DC, area,
• on leave without pay, or
• on an alternative work schedule (AWS) day off.

Telework-Ready Employees who are scheduled to perform telework on the day of the announcement or who are required to perform unscheduled telework on a day when Federal offices are closed to the public must telework the entire workday or request leave, or a combination of both, in accordance with their agencies' policies and procedures, subject to any applicable collective bargaining requirements.
Emergency Employees are expected to report to their worksites unless otherwise directed by their agencies.
