Today, there's a strange new badge of honor for professionals everywhere. It's not about promotions or pay, it's not about the company car or the holiday home, and it's definitely not about long vacation leave or good health insurance. It's about something altogether more...masochistic. In fact, it barely seems something to brag about at all. Still in the office at 10 pm? Well, that's your bread and butter in our hyper-connected, always-on world.
