Final answer:
Hourly wages are not based on a performance bonus; they are a fixed rate paid per hour worked, differing from performance-based compensation methods such as piece rate, profit sharing, or revenue sharing.
Step-by-step explanation:
The compensation method that is not based on a performance bonus among the options provided is hourly wages. Hourly wages are a fixed rate paid for each hour worked, and they do not typically vary with the worker's productivity or the profits of the company. In contrast, piece rate, profit sharing, and revenue sharing are all methods that provide compensation based on performance, productivity, or the company's success.
