Companies will eventually go back to being mostly in offices.
For some companies, that type of office setup has truly ended. Some companies will end up with some sort of hybrid. A smaller office base with desks being used as and when needed. Some will want / need to be in the office full time, others far less.
There are so many "cracks" in areas like customer service, staff training, efficiency, etc., that quite a lot of firms/staff will need to go back towards the old ways. It will have highlighted which roles are ideally suited for homeworking, which roles need bums on seats in an office, and which roles can be done with a mixed working pattern.
People thinking/hoping that WFH will be the new normal across the board or that occasional popping in to a hotdesk environment for all office workers are in for a nasty surprise.
Customer satisfaction is at an all time low, efficiency is suffering, etc at many firms, especially B2C firms which deal with the general public. B2B firms, technical roles, and back office functions are more suited to WFH with occasional business trips/office visits as necessary.
