Explanation:

1. Usually wages are paid by the number of hours spent working.

For example, someone who works as a warehouse supervisor may be paid hourly for the amount of time spent on the job.

For example, a person may be paid $15,000 (fixed amount) each month not necessarily considering the number of hours spent on job.

Annual bonuses or commissions, life insurance etc.
