I agree with the lack of commute, but the phrase used was in relation to 'working much less' which is a criticism often targeted at those (including me!) who have the ability to work from home. In my experience, those who WFH are more productive, and actually spend more time working than they would in the office because of that lack of commute, and for other reasons.
Certainly, having done nights every cycle for years (along with a 1hr40 commute each way) earlier in my career, I know the impact of them, but my post wasn't about that.
My point is that fatigue affects us all individually, in different ways. Reducing things to a 'shiftworkers have it worse, office workers have it easy' while claiming office workers work less is just facile and doesn't help anyone.
I'll be some years behind you, but also looking forward to it!
