Casey did the right thing!!
I ran into a few instances as a kid very similar... One that sticks out was when I was 12 picking Blueberries for the summer with my cousin. We'd get up at 4:30am to be on the berry bus and would spend our 9 hours a day picking...
On that berry bus there were many older than us, thinking back we were probably the youngest working there.
As a berry picker, they give you a row and the Berry boss inspected the bushes as you picked along. If you left ripe berries behind, they'd pull you back to finish that bush... Well being 12, we didn't have the fastest hands in the world. Considering the job in discussion, we certainly were the minority. There was a group of guys that were 18-24 that would constantly pick ahead and then "ream" our bushes. Meaning, they'd pick all the bushels of berries that were easy to get to off of our bushes...
After a few weeks of being "picked on" my cousin and I decided to stand up for ourselves and tattled on them. That did us no good, matter of fact that made that berry bus ride in the mornings the worst. They'd constantly pick at us and bully us around....
Finally about half way through the season, my cousin and I had had enough. We decided to stand our ground. As we sat on the bus that morning and those guys started picking on us, we lost it... I remember going over the seat behind me and kicking the biggest guy in the head and when he fell to the center aisle I remember punching then kicking him in the face and that's when the berry bus came to a screaching hault...
Long story short, you guessed it. We got fired and weren't allowed on the berry bus again and weren't allowed to go back to work there... Looking back, that sure sucked losing that $3.00 an hour job...

But I'll gaurantee the gratitude from beating the bejesus out of those dudes bloodying their faces, was a positive influence in life....
Stand your ground. That simple...
