Of particular interest from a group dynamics standpoint were the social pressures used to gain compliance with the group norms. The incentive system dictated that the more a worker produced, the more money the worker would earn. Also, the best producers would be laid off last, and thus they could be more secure by producing more. Yet, in the face of this management rationale, almost all the workers restricted output. Social ostracism, ridicule, and name-calling were the major sanctions used by the group to enforce this restriction. In some instances, actual physical pressure in the form of a game called "binging" was applied. In the game, a worker would be hit as hard as possible, with the privilege of returning one "bing," or hit. Forcing rate-busters to play the game became an effective sanction. These group pressures had a tremendous impact on all the workers. Social ostracism was more effective in gaining compliance with the informal group norm than money and security were in attaining the scientifically derived management norm.
