I had this problem too. On the advice of a fiend I started shutting down the work computer before dinner. That puts up a barrier to "just checking in" when you should instead be devoting some time to yourself, your family or friends.

If you don't have a separate computer for work then maybe a separate login would help in a similar fashion. Since the physical (distance) separation isn't there you have to find a way to create something similar.

I've had this issue in the past, but with my current employer, I have less of an issue.

I'm on the east coast. Most of my direct co-workers are on the west coast. I typically work from 06:00 to 09:00, then perhaps do other stuff for a few hours, then work again for a few hours in the afternoon. Then, depending on work load, I may get back at it for a few hours once my kids are asleep, which still allows me to interact with people on the west coast.

Its better to sometimes get paged at home for work than to hearing that "I'll need you to work till late today" or "We need you to come in the weekend" when working on an office.

And depending on your work, you'd probably get paged at home even if you work at an office anyway.

In some ways you have to accept the boundary is blurred, and try to enjoy that.

I have a separate physical office on the property, and at night I take a laptop into the house, but never work long enough that the battery runs out.

I feel the same way, but I had started to notice this even before I started working from home, thanks to the blackberry. How many times have you been eating dinner with others (at home, or a restaurant) and felt compelled to check it, and then guilty about what you are doing?
