Despite years of encouragement for teleworking from OPM, GSA, some in Congress and some outside groups, resistance of managers remains a major impediment to broader use of telework, according to a survey. The survey, conducted by the Telework Exchange—one of those outside groups—found that fear of not having control over employees’ activities, productivity concerns and security concerns are the major impediments to telecommuting. Communication issues–lack of face-to-face contact, inability to personally collaborate and lack of access to co-workers–also were cited, as were issues such as inability to track work being completed, employees not being available for last-minute projects, and lack of support from top management. Only 35 percent of the managers responding to the survey said their agency supports telecommuting, 47 percent said it doesn’t and the rest were unsure.
