24/7

Most of my work is done on line these days. And Im surprised at how many people expect me to be available 24/7, answering emails as soon as they arrive night or day.

It wasn't too long ago that people tended to work a fixed timetable. Once the work was done, they headed home and that was it for the day.

But the rise of internet, online shopping and banking and other always on services has given us this idea that everything should be available all of the time. And that's where the expression "24/7" comes in.

When something's 24/7, you can pretty much guarantee that it's always available, or that a service is offered all day without interruption around clock.

The Oxford English Dictionary first included "24/7" way back in 1983. But its only in recent years that its becoming so widespread, covering shops, websites and even people.

These days you might even find 24/7/365, meaning that a service is available every day of the year, which more or less describes my work routine.
