Oh no Shoe, do not give in to the urge to check work stuff in your off hours! Trust me, I work from home & have access to my work email 24/7...I have been through this..at first I thought it was cool to check in at the evenings & weekends, just in case I was missing something, but soon found out it becomes obsessive, it was demanding and totatlly wasteful of my free time....so I stopped. Now when I log off work around 4pm I do not check till the next day & on Fridays --- it's gone till Monday, heck, they don't pay you to look at it!!

Sorry you friend is being hounded...sounds a totally mean & horrible thing to do to someone.
