I've been having similar thoughts. The company I work for already had a general policy that working remotely one day a week was fine, provided permission was granted by the relevant line manager. This day was primarily to be used for focusing on writing papers (company is positioned in the grey ground between commercial and academic worlds). However, over the last three months with everyone remote, all the time, it's worked generally well, apart from when access to the labs or R&D plant was required. I've been missing some of the face to face interactions, and meeting in person can move some discussions forward quicker. My volume of email has dramatically increased. In the future, I can see two or three days per week remote working being completely plausible and healthy for productive work. A couple of days per week in the office will still be useful for access to specialist equipment, personal networking and team building.
