I work for a financial institution and we're expected to take them home. That way, in the event of a natural disaster or extended power outage or whatnot, we're still able to work if needed.
I code for the core financial system (staff facing and back end processes, as opposed to member facing programs such as online banking). We don't have an on call rotation, but it's still been useful the times where I've got called after hours or on weekends to do some troubleshooting.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
