I quite enjoy it to be honest.
I was already doing approx 1-3 days a fortnight from home anyway when it suited me.
We got sent home fulltime on 16/3. Been home ever since.
I got my boss's permission to bring home my 2 big monitors, & nice comfy office chair. So glad I did.
For my actual role, it doesn't make much difference where I work - my boss is in Adelaide and rest of my team are in Perth, Sydney, Brisbane & Melbourne.
I deal with various people spread across the country & also our "extended workforce" over in India.
So the I guess only thing I miss is the day to day contact with the people from other parts of the company that I normally share the office here with - I have worked alongside and with many of them for 25 years.
Actually I also miss the free air-conditioning - My 'study' only has a dodgy old box aircon. Summer is threatening to be a bitch this year.
The family can be distracting at times - eg. wife often watching some shoot-em-up police show when she's not at work, but I do have a noise cancelling headset that helps
It's really not much worse than the open plan office for distractions.
Healthwise, it has been much better. No smoko van to tempt me with those evil pies & greasy deep fried treats. I start earlier than I used to, so can finish earlier & can get out & exercise & lose the spare tyre.
