I was thinking about this, and I could see it working if they downgrade to a smaller office without permanent seating. Try to figure out roughly what percent of total employees would come in on average.

This is what my company is planning. They plan on having a website where we can schedule office time with an open desk if and when we want or need to go in.

I do. I think something like this could become a competitive differentiator (smoother collaboration when you need it) and recruiting tool.
