When I worked in an office I never worried about being the first to leave, and didn't even realize other people do.
For me, the biggest downside of working from home is how easy it is to get distracted by non-work. I go grab a coffee and end up putting dishes away, cleaning up, etc. and next thing I know an hour's passed by so I'm working late or feeling guilty.
I've been working on my time management, in general, and that's helping.
Sometimes taking a short break like that is the best way to make progress on a difficult problem though. Realistically we probably get 2 or 3 hours of actual work done in a day. Everything else is a bonus and it comes and goes over time.
A lot of it is scarcity vs abundance mindset. Many people are quite scared to lose their jobs. I know people making six figures who would be in deep shit if they had a month of no paychecks while switching jobs.
The two extremes are: 1. Working as hard as possible to get a promotion over the next person working as hard as possible. 2. Doing the bare minimum to not get fired.
Anything in between is, logically, irrational, because you're doing more work than necessary.
Luckily, companies have found the levers for most humans and tend to get them working in between the two extremes.
That’s the unfortunate part.
WFH at large can only sustain if that hard line is drawn - end work day for good, disconnect, connect back tomorrow morning!
No fluid working hours and being ready to “jump back in”.
