That is also what I noticed about my coworkers in my previous job: either they will go to the arena for cockfighting or they will go to other places to get drunk. I feel that they are not tired of doing it, no matter how busy the work is. Even I can't do it, as I want to rest after the work unless it is not a busy day on which I still have spare energy. Though I wouldn't say that they are addicted, as they can still control themselves, it is just part of their daily routine to do it.
Perhaps your coworkers find joy in gambling as their hobby or past time every time after work. As long as they are responsible and do everything well in your workplace, then it's all good. Time, money, effort, and of course funds, are essential in gambling. If they have enough spare of those and doesn't bypass their other duties and tasks as a family member, friend, workmate, and the likes, then we shouldn't intervene. But if it's the otherwise, we could give a feedback and a caring opinion.
As long you would really be that responsible
As long you do know on how to handle your finances
Then you should really be fine. You cant really be finding yourself to be addicted on gambling anytime soon no matter how long you would be engaging into it.
Most errors or mistakes on which a certain person is on the time that they would be passing out on their senses on doing the right thing. They would really be just simply be
focusing on what they are currently dealing despite on having a hug losses already.
You wouldnt really be getting addicted if you are rally just having those border lines or boundaries or simply limits in towards self on everything you are dealing with.
