a. This Headquarters Procedural Requirement (HQPR) directive sets forth the hours of duty and tours of duty available to Headquarters (HQ) employees. In addition, the document establishes the responsibilities, procedures and requirements for determining work schedules in accordance with applicable laws and regulations, including reporting requirements for the Web Based Time and Attendance Distribution System (WebTADS).

b. NASA HQ supports programs that strengthen the strategic management of human capital, foster cooperation among all employees, increase employee productivity, and support the ability to attract and retain a diverse and talented workforce. Accordingly, it is NASA HQ policy to support employee participation in alternative work schedule (AWS) when they are compatible with the accomplishment of organizational requirements and when the duties and responsibilities of individual positions lend themselves to such work arrangements.

The terms: "may" or "an" denote discretionary privilege or permission, "should" denoted a good practice and is recommended, but not required, "will" denotes expected outcome, and "are/is" denotes descriptive material.

The HQ Human Resources Management Division (HRMD) will gather and track data on various work schedules used by employees and analyze the data for trends and problem areas. In addition, findings and trends from Office of Personnel Management (OPM) employee surveys will be used to assess employee satisfaction with the availability of AWS. This data will be evaluated to identify areas of success as well as areas in need of improvement. Appropriate action(s) will be taken to address concerns raised to ensure that NASA HQ maintains a positive performance culture.
