Managerial accounting Under N.L. Gantt's scheme, time wages are guaranteed to every worker. Standards are set. Bonus is generally 20% at 100% efficiency. If a worker takes the standard time to perform the task (100% efficiency), he is given wages for standard time and bonus of 20% on wages earned. If the worker completes the task in less than standard time he is given wages for the standard time (for actual output) and a bonus of 20% of the wages for the standard time. A high piece rate may also be offered for performance above 100% efficiency.
