head-down
adj.— «An in-depth corporate workplace survey showed that the main problems for those working in traditional eight- by nine-foot cubes was the lack of privacy and difficulty in doing heads-down work. For employees who had already been moved to six- by eight-foot cubes the problem was worse. Not only was heads-down work more difficult, but collaboration was also hindered because informal meetings were more disruptive for those working nearby.» —“Intel’s Workplace Environment Program: Confronting the Conflict Between Cost and Effectiveness” by Dave De Long Accenture Oct. 26, 2001.
