My biggest issue with WFH is that my employer won't commit to it fully. Meaning we're indefinitely WFH until we could be recalled to RTO without significant warning. Thus, I need to maintain a commute-ready vehicle, and live in a more expensive area so that hypothetically I could commute.
The actual work is exactly the same, but with fewer people disturbing me, a two hour shorter work-day (commute), and the ability to e.g. listen to music while I work, or have a TV show on in the background. Plus it has forced my managers to better define expectations because they cannot use nebulous "butt in seat" tracking.
I seem to get sick less (colds, flu, etc), my stress has never been lower, and communications with colleagues has improved as people have learned to use text-chat, and important meetings have a text transcript.
