Answer:
Merit pay
Step-by-step explanation:
Merit pay can be defined as a payment that is performance related. It is a form of payment or benefits for an individual that attains a certain high target.
For example, companies use merit pay as bonuses for employees that meet extraordinary targets within a period of time.
For Janelle in the question above, $500 is a payment for having an appraisal score of 4.0. This means that if Janelle has an appraisal score lover than 4.0, she would not get $500.
Cheers.
