It's simple to decide because when principled yourself you would be able to work over there and still not gambling determining your interest.

I have a friend who is a staff in a local gambling site, she doesn't gamble when I asked her she said her interest is not to gamble there but to save money to sustain her family and save for her up keep, this made me saying that it depends on personal choice and decision to gamble or not.

Although it depends, if the person is already a gambler and got employed it could be very hard for that person to control themselves but if not a gambler then the person can be able to make savings without touching their salary or even think of gambling.
