So you've accused the previous poster of bad absolutism, and then you do the same in saying that WFH is more productive....
My experience of WFH in my company is that individual tasks get done effectively, but the easy communication that people sitting in the same office use to grease the wheels of tasks that aren't simple tick box exercises disappears, so overall productivity reduces. The extra effort of having to call someone to ask a question means that people often park their questions for a later call, which holds up the task, or they struggle on on their own, which also holds up the task.
I have been on the direct receiving end of inefficiency on the part of HMRC and a number of financial institutions, where the work from home directive has caused all sorts of problems that they appear to unable to resolve. Anecdotally, i have heard of lot of companies having major medium and long term issues caused by working from home.
My personal view is that work from home is effective for certain industries and tasks, but it won't take long for companies to ask people to return to the office once they are allowed to do so for productivity, social and welfare reasons. I think there is a big work from home car crash about to happen for lots of companies.
Some people love being able to work from home and tell the world how great it is for productivity, even when it isn't. However, there is also a significant percentage of those currently being asked to work from home who hate it and can't wait for the current WFH guidance to end.
