Yeah, I wouldn't mix up my work and my hobbies. Each needs concentration, whereas doing both would break it.
It's an increasing trouble and players neglect the need to stay responsible. Most players lose productivity in their work place. Because they're gambling at work. That's addiction in a high level. However, if a player decides to make such mistake, he's risking his job opportunity. Gambling is not meant to be misused. It's meant for relaxation after work, not during work.
And it should stay that way for a long time.
Luckily, I have never bumped into online gambling while I am still working a day job in an office because if I did, I might do that kind of thing and it would be a waste of time and money which also jeopardizes my job.
We cannot combine these two. The work should be done first and after that, it is when we can finally relax and enjoy gambling more because we have nothing else to think about.
Truly, it's a different level of addiction because a gambler cannot control himself anymore and he is bringing his bad habit to work which could lead to being suspended or maybe worse.
