At Work

This is why I still resist, and will continue to resist, a Blackberry - because you are never not at work.

The theory is that they help you get things done and support flexible working.

Yes, they do to an extent but what I see is that they generate stress. People work hours they don't get paid for and I would love to see somebody research how effective they are at getting things done.

As far as I can see, the amount of time people spend on them outside work hours is disproportionate to what this actually achieves. They do not enable quality work, they only allow you to react which just means more unnecessary emails and more work.

If you want to be efficient you actually need to switch off at some point!
