Well, I work from home anyway, but now I also have 2 teenagers home from school, and my wife has to work from home now. She's an IT help desk person herself, so it was easy for her to get running from home. About 99% of her support tickets have been setting up other people to work from home. She said you can hear screaming kids in the background of a lot of her calls.
For the teenagers, we decided that even though they don't have to go to school, we are going to try and keep a normal Monday-Friday schedule of waking up early and having a routine. The kids and I, have a morning meeting at 8am to plan out the day into blocks of chores, schoolwork, and recreation activities. Basically I let them decide what they want to do that day and they write it on a white board. They aren't allowed to stream videos or online game until after 5pm so that our bandwidth doesn't get choked up while my wife is working.
My son and I built a rig for his poor friend out of some rather nice older leftover parts we had laying around. We bought about $10 worth of games from GOG (so many you can get for $10), and we are getting them installed. I think tomorrow we will be delivering that.
My wife and I used to go to the gym every day on our lunch break. Now we just do our strength training at home and jog at the park when she gets done working. I swear it's already summer weather here on the Gulf Coast, and Winter isn't even officially over yet. Been running around shirtless at the park and sweating my ass off...
Making new routines keeps you sane.
