Well I know the insurance industry productivity is 75% of what it was pre Covid, problems with security and access when employees trying to access data from unsecure home workspaces, no immediate IT backup, no "handholding" employees through problems by experienced colleagues. Therefore if a problem can't be solved by the employee at home they have nothing to do for the day, also good excuse if you don't want to work. In other words real world stuff that is not sexy to talk about. I doubt the ESRI is going to do a comprehensive study of productivity from WFH because they might get the wrong answer and it would also conflict with the government message on reducing Corona . maybe next year when they want get the real economy back up and running.
