Is working as a supervisor of collectors in an amusement park, without handling money, unlawful (haram)?

If amusement parks are recreational games free from religious prohibitions such as gambling, obscene images, and music, then there is no harm in working in them. However, if they include religious prohibitions and working in them constitutes aiding in sin, then it is forbidden, as Allah Almighty says: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
