ABSTRACT
The conditions likely to affect labour efficiency discussed in previous chapters were all conditions confronting a worker at his place of work. Efficiency, however, is the product of the worker's characteristics as well as those of the work place. With the same factory hours, type of work, physical and social conditions, and the same wage and method of wage payment, two different individual workers may yet show very different efficiency: one worker may be more efficient generally than another, or one may be more efficient in one line, the other in another line. Inherent quantitative and qualitative differences in the intelligence as well as the physical make-up of individuals were described in Chapter I and form the basis (together with the more obvious variations between workers in attainments due to education or experience) for now examining the selection and training of workers as further conditions likely to affect efficiency.
