When workers with traditional skills are faced with highly advanced machinery and equipment as working partners, they find difficulty, when required, in overriding machine operation, or decisions. The workers feel diminished, feel that responsibilities are removed from them, and that machines set an intolerable pace independent of human decision-making. Employers do not know what skills are required in automated and semi-automated operations for workers, often do not hire the right people, and usually provide training inadequate to instil a sense of security and competence in those that are involved in the man-machine interface. There is both a human and a financial cost to such worker maladjustment.
