I think it's that attitude (of your production manager) that will be consigned to the dustbin of history. Some managers seem to think that if they're not directly looking at people for 8 hours a day, then no work would get done.
The reality is that, in most jobs, there's a certain amount of work that needs to be done to a particular standard by a certain time. It obviously doesn't apply to all jobs but, for the vast majority of people, they are both capable and trustworthy enough to undertake that work from home. For those that aren't, remote working actually makes it easier for a manager to differentiate between individual performance and team performance, facilitating the necessary management action.
Organisations have now invested far too much into remote working, through new hardware (laptops, etc), increased network capacity and new working practices. They won't just want to rip that up and return to 'normal' and they'll also want to make savings in office space, travel, heating and lighting, etc.
I can envisage the new world being one of predominantly home working for most office staff, with office time being limited to essential meetings and some staff welfare (i.e. a bit of human contact).
