Our building security system updates something somewhere which ties into email. When we have incidents such as "the lifts are broken" or "the south exit is closed" or whatever, these get emailed to all staff that have been in the the building in the last so many hours (16 I'd assume). It's a handy system.

Ultimately if you are at the type of company which practices presenteeism, then the technology used is immaterial
