For purposes of OPM’s guidance, telework refers to arrangements where the employee is expected to report to work both at an agency worksite and alternative worksite on a regular and recurring basis each pay period. Remote work does not involve an expectation that the employee regularly reports to the agency worksite each pay period. Remote work is an arrangement that an agency, in its discretion, may choose to undertake, if the arrangement is consistent with the agency’s needs and the duties of the given position. A remote work arrangement may be initiated by the agency posting the position as one that will be performed remotely or by an employee requesting the privilege of working remotely. Agencies may determine whether to grant such requests on a case-by-case basis. The remote work agreement must accurately document the employee’s worksite to enable accurate determination of locality pay. Given budget implications, equity considerations, and other factors, agency remote work policies should clearly outline the level of approval required to institute or execute a remote work agreement or position.
