During the crisis of World War II restriction of output became a matter of national concern; the drive for production caused much attention to be focused upon all practices limiting industrial output, but no practice was more thoroughly condemned than regulated "holding down" of production. Becoming aware that workers do not always produce to full capacity, the general public accused those not doing so of being unpatriotic, of "tralling down on the job". With the ending of the war, restriction of output has been dropped from the editorial pages of the newspapers, but to students of factory social organization certain implications of the practice are of continuing importance.
