Answer:
Mentally thinking youre not worhy
Step-by-step explanation:
When you have a skillset, and you work with people/s with the same skillset, but they get a higher pay than you even though your skills are equal, it could potentially hurt you mentally and make you feel like you aren't worth what you actually are, and you might not try to climb the ladder and find higher paying jobs because you dont think your worhy, or fear of rejection.
