> What data do you have to support this, other than a personal anecdote?

If RTO proponents had any hard data, wouldn't they shared it by now? It is _they_ who are making the claim that office work is more productive, so it is on them to _prove_ it. We are being fed some fables about "spontaneous interactions at water cooler" and other such bullshit instead.

Well - at my massive company no one is willing to share any data about these decisions. That's a huge red flag. And anecdotes about remote working are personal (individual manager) and larger team (100s) to entire orgs (500+). it's been working great.
