Having worked full-time remote for more than two years so far (and part-time remote before that) I agree with the conclusion that remote workers are no less productive than on-site employees, but that the trade off can be frustration and feeling disconnected.

I would actually say I am more productive at home (no commute, fewer in-person distractions, comfort of having my own kitchen and making coffee my way).

When I go into the office for occasional on-site meetings, I definitely feel more invigorated and energized from being around people and collaborating on a shared vision, at the expense of being able to focus deeply and get concentration-heavy work done.

I think it's about striking the right balance, and having a company that strives to enable the remote teams (especially important if you are a hybrid on-site/remote company)

I'm overall happy with the mix/ratio, and I think what helps is that we're always striving to improve wherever possible.
