This is one of those situations where one size will never fit all. There is no real 50/50 on views - either it works for a particular role or it doesn't. Of course there can be expectations for everyone to go in 2 days a week for meetings or whatever, but the act of wfh is the same whether it would suit you (generic) me or anyone else. It suited me long before Covid to spend some time wfh, as it meant that I could work uninterrupted by colleagues and students, and power through marking or research. At other times I had to be on site. Obviously for lectures and meetings - few people used Zoom or Teams then - and to be available to students. I was perfectly capable of deciding for myself when to do what, and would have resented someone else thinking they knew better than I did about what was appropriate for me.
As ever, where Farage is concerned I would follow the money. What is his financial interest in office blocks and/or places where office workers shop for coffee and go for lunch? There has to be some reason why he can possibly want a blanket policy for something as varied as 'workplaces in Britain'.
There are comments on news sites from individuals who are clearly jealous of people who have jobs that enable them to wfh - usually couched in 'what about all those who can't do it?' terms that take zero account of logic, and others who take an 'I had to commute for 40 years, so why shouldn't they?' approach, which is equally idiotic. Modern technology allows some people to wfh, so why shouldn't they if they want to?
If someone prefers the social side of working with others, they should be able to go in, and should seek employment that makes it likely that others will do likewise, but if someone else finds that they can get the job done and still be able to make their domestic life work, then they should have that option, too. If for some reason people are unable to find the role that suits them, that is unfortunate, but no reason to deny others the option to do what works for them. Having others work at home reduces the amount of traffic on the roads/passengers on buses and trains, so makes life easier for those who have to be on site in any case.
If the job is not getting done because the worker is at home and not working, that is for management to deal with. I am not suggesting that people should have free rein to laze about, but I think it is important to recognise that not everyone in an office is pulling their weight either. Many discussion boards with younger members are busiest during office hours, and have been for as long as I have been using them (early 2000s). Many people book holidays, order shopping, post on MN (and elsewhere) and more during working hours in the office - skiving is not confined to working from home.
How would Farage impose a ban on wfh anyway? Many workplaces have closed offices or reduced the number of workstations.
