OPM has issued guidance on the Inauguration Day Holiday that will apply on January 20 to federal employees working in the District of Columbia, Montgomery or Prince George’s Counties in Maryland, Arlington or Fairfax Counties in Virginia, or the cities of Alexandria or Falls Church in Virginia.
It says that employees "must be in a pay status or a paid time off status (i.e., leave, compensatory time off, or credit hours) on their scheduled workdays either before or after Inauguration Day in order to be entitled to pay for that day if they do not work. The holiday does not apply to an employee who is on official duty away from the official worksite or travel status away from the Inauguration Day area, even if his or her official worksite is in the Inauguration Day area. For those employees, Inauguration Day is treated as a regular workday. On the other hand, the Inauguration Day holiday applies to an employee whose official worksite is outside the Inauguration Day area but who is in travel status or otherwise working in the Inauguration Day area on Inauguration Day."
The guidance, which also covers other issues such as alternative work schedules and telework arrangements, is at http://www.chcoc.gov/Transmittals/TransmittalDetails.aspx?TransmittalID=1910
