In this factory a number of engineering production lines are operated. The direct labour force is paid on a time rate basis, but a bonus is paid if work can be completed faster than the time allowed. The bonus is for the savings achieved to be shared equally between employer and employee. Wages are, therefore, paid on the following basis: time rate + 50% of (time saved x time rate). If no bonus is due, then the time rate applies.
