Avantages
Moderate working environment. Possible to learn new things, even when it's not your responsibility or your area of interest. If you like to work, you will be given a lot of works & you probably needs to stay office even it's weekend. So for those who only like to work, it's your heaven.
Inconvénients
Employee needs to be alert 24/7 or whenever needed. No hope for the professionals & strong politically nasty environment. Even employees need to make business trip while in weekend, because you need to be onsite on weekdays. Balancing work & personal life is kind of impossible while you are a active worker. If you aren't working, that's also fine.
