i don't do filing. Problem solved!
I think the concern is having them come to YOUR home office, rather than the other way around (as much). On the rare occasion that I have had to go to their office, my hubby knows my schedule for how long I should be there, where specifically I am going, and I call him when I arrive and when I leave. If he doesn't hear from me in a reasonable time he will call me on my cell (hasn't happened yet). If he can't reach me, the next phone call will be to the police.
We also have a 'code phrase' that means I'm in trouble, just in case. I won't reveal it in writing but it's best to make up your own anyway; something that you wouldn't say in a normal conversation like "I'll pick up the cat's pills on my way home" (we don't HAVE a cat!). This phrase would absolutely trigger him to call the police ASAP!
And I let my clients know that my hubby has my schedule so if he calls I will need to answer my cell so he 'isn't concerned that the can't reach me.'
