Individual principles are still influenced by the working environment, when we are in a certain field, knowledge and acquisition are relatively important but digging deeper, people realize many ways to exploit resources in their work, when this is clearly their advantage, with years of experience, thinking about a win in the casino is not an illusion but the nature of the work and passion is addictive. Addiction in any other area can be a good thing but addiction in gambling, low productivity and gambling environment becomes a place for us to destroy our lives.
I think a casino employee could and most likely also gamble. but the gambling activities they do may only be to relieve stress from their work. not to make a profit. environmental influences must be big enough to make them gamblers too. they have experience and eventually will not be able to resist. but not as active gamblers. more of them must only seek pleasure in gambling which is done not for profit or even seeking victory.
of course, the situation experienced by each person is different depending on the character of the person. if there is a casino employee who is addicted to gambling. maybe it is bad for his career. their salary must be quite large, and it would be crazy if they also spent the money they got from the casino to play casino.
