Are there studies that prove that working from the office is more effective? You must have studies proving this, as I'm sure you're not advocating for collectively wasting billions of hours of time each week on commuting "because we've always done it that way". Surely.

It takes a loooooooonnnnnggggg time to published peer reviewed research, and the better studies will need to compare pre vs post so I wouldn't expect them till next year, at least.

Yup. Everyone is saying remote work is better. But there are no studies to prove that it is.

'Better' is not measurable. What metric are you after?

As an employer I bet 'productivity' is your main driver.

An employee of yours would probably say 'quality of life'.
