Yes, there have been lots of posts around this subject and others saying, well, of course, it's just the norm. The current global pandemic is so far from the norm, everything and everyone is disrupted. You are not 'working from home' - you are 'working through a crisis at home'. Here are my tips from experience in working remotely (from home), and running a busy household with three children.
Looking back at my career - when I first started working from home, rather than having a healthy mental approach to it I think I overcompensated; working longer hours, not taking time out of the day to have regular breaks or exercise.
I felt I really 'should' be in the office, so I need to demonstrate "I going above and beyond anyone else". No one will be able to say I am not working hard. As such, I didn't do all the things I am going to detail here and often felt 'exhausted' and not energised by my 'favourable' situation.
Time has moved on, and now obviously working remotely / from home is very much part of many people's working week. However, the current COVID-19 crisis has meant there are lots of people that maybe not so accustomed with a more frequent / or indeed full time working from home policy that are adjusting to the new norm.
