Who cares about any of that? He was being paid. It was not a charity, it was work.
Companies don't owe you anything. (And you don't owe them anything, either.)
Work is a temporary agreement to provide services in exchange for money. That's it. Understand how the world works.
People who understand society care about it. When you employ someone you take on a certain responsibility. You can't negate that by pretending that you're in an equal power relationship.
That's why we have workers' rights.
