I think the important distinction for us is that it isn't "work from the office one day a week". It's work from home unless your team needs you. Our ask is that team leaders work very hard to limit the days that people need to be in the office and that when they ask folks to come in there is a clearly articulated reason and objective. Basically the idea is that we want coming into the office to feel valuable and therefore worthwhile.

In reality most teams don't need people to come in that often... I'm concerned about some long term drift where some teams never come in and others find themselves schlepping into the office a lot, but I think it's something we can manage with good coaching for our team leads.
