Yeah, although the thing is that if you manage to do those things in a more controlled way, you might be able to get away with it.
If you only gamble at work from time to time, it's not really a big deal.
Even if anyone is able to handle the office work perfectly and at the same time, they gamble within office during the office hours but does ti allowed by the office ?
I mean will the office give this permission to employees to gamble and do other task while they are at work ? Most of the gamblers will not tell their bosses that they are doing gambling and will be doing it hiddenly. I think no one even have the dare to disclose that he is gambling at work ?
The issue appears when you start consuming too much time. That's the key. Because you lose focus and attention, which are critical and scarce resources.
Of course if you start to give more time to gambling and less time and focus to the office work, it will not only affect your own performance but at the same time, it will have a bad impact on the overall business from whom we are being hired to work on. I still think if you are sincere to your work, do not gamble at the work time. Better dedicate full time to work during the working hours and when you want to gamble, you should not be at the office. There are ample time after office hours where you can gamble and enjoy.
