This unstoppable trooper keeps going and going and going, working late every night and getting in early the next day. Known to send work-related e-mails on weekends at 3 a.m. (marked URGENT), and always arriving at the office despite the snowstorm/transit strike/earthquake/appendix operation -- whether it's Thanksgiving, Christmas Day, or New Year's Eve.

aka: The Terminator, Old Faithful, Ms. No-Life

How to handle: You can't compete. Just keep a positive attitude and don't feel obligated to work late nights, weekends, or holidays without overtime.
