I Really Don't Mean to Harp on This
But if you're not thinking about telecommuting as a key component of your pandemic influenza preparedness planning, I don't even know what to say about it. When you have the tools for people to be in touch and productive from wherever they are, that's a good first step. But you also need to empower people to STAY HOME when they first feel iffy, rather than soldiering through another day a little bit achy.
Dig it: when you're a little bit achy (but not that sick) you are most likely at your most contagious.
So you come into work a little under the weather but still functional, and then you proceed to touch stuff and breathe on people all day until you give up. Then the next day you have a fever and you're really sick, but friends, the damage is done.
As an alternate approach, you could have access to robust telecommuting tools that allow you to be as good out of the office as you are in. You have a laptop, you can connect to your phone system and forward your desk phone to where you are, your VPN is pre-installed and all you need do is connect to see all your network stuff just as though you're there. And your boss knows this and will expect you to be in touch just like you are in the office as long as you're only mildly ill.
You're home just infecting yourself and your family. And that's better for the rest of us.
