there is actually something I forget to mention about my working at home.
I use a free service called rescue time to monitor how much work I'm actually doing
it is really awesome, and helps me make sure that i'm give the company I contract to a fair deal.
it records the time you spend in each window/application, and then you can tag the applications as work or other things
it then shows graphs of how much time you spent at your computer, and how much was work vs. other
Companies can sign up and monitor employees that way.
Maybe if your company used this, they would have evidence for you saying that you do in fact work at home.
if you don't have the time to do it right, when will you have the time to do it over ?
