- The plant manager noticed a need for reducing the amount of waste materials which occurred in the production process. A task force was set up, comprising of the plant manager himself and two of his supervisors, to examine the problem. They met for three months and published the task force objectives, and findings on the plant bulletin board regularly. The plant manager found out to his surprise that the workers on the shop floor showed very limited interest in the task force and ignored the bulletin board entirely. At the end of the three-month period, the task force came up with several excellent recommendations, which require changes in work practices. Most of the workers implemented the recommended changes very reluctantly and some even secretly worked to sabotage the new practices. Eventually, all recommendations were withdrawn. What went wrong? How should the plant manager have handled this case
