But if this is not the case then you could get in trouble, as even if taking a small break here and there is also not something anyone will make a fuss about it, if you are often caught gambling or watching some youtube videos you could get fired, or at least you could get on the short list of those that have the power to take that decision.
Listening to the music or radio is also done in entertainment purposes. Should employees then sit in silence whole day?
Gambling activities can make you forget your responsibilities, the adrenaline produced when gambling is very different from just reading or watching videos on YouTube. You will become more immersed in the atmosphere, especially when you are lucky, your mind will be increasingly encouraged to continue betting due to the positive adrenaline produced by the hope of getting a bigger win.
Once again. I dont support going to work, opening casino in browser and gamble for the whole working day, with making pauses to work a little and coffee breaks. I dont support gambling at work when from your work other persons life is endangered or he can get injured. I dont support gambling at work when you work in government institution for example.
But I see not problem to make a 5-10 min gambling session at work, when you have done your current tasks, you dont have any future future tasks, and you dont bother others work.
