Ironically wfh is a consequence here of our current disastrous state as an organisation. In order to cut costs we’ve consolidated into a small number of buildings that can’t accommodate every office worker, so we’re actively encouraged to work off site one day a week.
I do Wednesdays, which breaks the working week up nicely. On a good week the Monday inertia + Tuesday winddown + Wednesday nap + Thursday inertia + Friday winddown can result in almost nothing getting done.
