As a non European working for a European company, it is an interesting experience with non work times. The laws around working more than 8 hours a day are incredibly strict, and the company and all the managers will never ask or expect an employee to work more than the 8 hours. Even if you are on call and end up having to work, you have to then take time off during the week to "make up" for the time you worked while on call.

Yet I'll be on call over a weekend trying to fix a problem at 2am, and my colleagues who aren't on call just drop in to help because they saw the alert and felt like helping out.

It is like people want to actually positively contribute to the well being of the company when they are able to, because the company doesn't try to drain every bit of will to live from their employees and respects that they are real people with lives.
