Federal Telework: Additional Controls Could Strengthen Telework Program Compliance and Data Reporting, GAO-17-247: Published: Feb 17, 2017. Publicly Released: Mar 20, 2017.

“How are federal agencies managing their 400,000+ teleworkers? The 4 agencies we reviewed (Ed, GSA, Labor & SEC) generally met the reporting requirements in the Telework Enhancement Act of 2010. However we found some barriers to telework program success:
Training timing: Managers may make telework decisions before training.
Documentation: Agencies may not review telework agreements annually or document renewals.
Managerial resistance: Some supervisors discourage telework despite agency participation goals.
Separately, we also found OPM and some agencies had quality problems with their telework data, which we made recommendations to address.”
