“The individual effort method of increasing the reward of the wage-earner includes all that is best in other methods, and attempts to exclude all that is objectionable. Its good points are summed up as follows:
# The standard time set is reasonable and one that can be reached without extraordinary effort, is in fact such time as a good foreman would demand.
# An extra reward of one-fifth of the regular wages for the operation is given to whoever makes standard time.
# Extra compensation above the hourly rate is paid even if standard time is not reached, although this extra compensation diminishes in percentage above standard time-and-a-half.
# If longer than time-and-a-half is taken, the regulai day rate is paid. Of this, the wage-earner is also sure.
# Standard time is carefully determined by observation and experiment, and is only changed when conditions change.
# The arrangement is one of mutual benefit to both parties — of increased earning to the worker, of increased saving to the employer.
# The employer loses more than the wage-earner if schedules do not encourage co-operation.
# The wage-earner, working on a schedule, becomes in a large degree his own foreman.
# The wage-earner determines his own earning power, and by co-operating to cut out wastes increases his own value.”
