MOTION STUDY
plane passing through the body. It is so necessary to
have the motions similar that often counterbalances and
springs can be installed to reverse the motion, thus also
causing the hardest work to be done in the most convenient
direction.
Anything that is used very often can be returned to
place better, as well as with less motions, by gravity, or by
the application of the gravity by some such means as a string
and a weight. It requires some skill to use a wrench, but
it requires no skilled motion or thought to return the wrench
to its exact resting place with handle pointing in the most
economical direction for picking up the next time it is used.
The average machine to-day is designed for a short
demonstration of quick output, with less regard for the
least percentage of rest required for overcoming fatigue
due to continuous operation. With demand will come
supply of machines that fulfill all economical motion re-
quirements.
Union Rules
The local rules of some unions are sometimes a hin-
drance to standardizing motions and thereby increasing
output. The higher wages from higher outputs under
intensive management soon convert the desirable members,
however.
Many unions believe that extremely high outputs per
man are against the interests of the union as a whole, on
the theory that they may “work all of their members out
of a job.” Furthermore, they often think that the sacri-
