How Managers for which type of employees use the amount of work completed to calculate the wages of an employee?

Managers typically use the amount of work completed to calculate wages for employees in roles that are paid on a piece-rate basis or commission-based positions. This approach is common in industries like manufacturing, agriculture, and sales, where output can be easily quantified. By linking pay to productivity, managers incentivize employees to increase their performance and efficiency. This method can motivate workers to maximize their output while directly aligning compensation with their contributions.
