When the Covid-19 pandemic hit pretty much the whole world sent into lockdown. This utterly changed the dynamic of how the world of business would work. Offices were no longer occupied. People were working remotely from home full time which is ok during the pandemic but in the long run, not so much.
While working from home seems like it would be a dream, the problem is that there is no longer a disconnect between work and personal life. There is also the lack of needed personal interaction of coworkers, zoom is not the same as physically being there. This is the same as our children needing to be back in school.
This is not to say that you cannot work from home ever but it should be one or two days per week (based on an 8 hour day), the bulk of time should be in the office. This is so that you get your collaboration, the separation of your work and personal life is still there. You also get that stimulation from being outside your house.
In addition to the personal and business benefits (the business you work for) there is also a benefit to the larger economy. One of the economic downfalls of people working from home is how many other businesses lose money which has a ripple effect. There is a lack of usage of public transportation, restaurant and other food establishments have less (or no) people ordering lunch. Retail establishments lose business due to the lack of traffic which is just drive by on the way to or from work.
While this may not seem like much it does have an overall impact on the number of employees businesses keep on board. It also creates shortages in supplies as businesses cut back on ordering products so manufacturing cuts back on what it produces. No business in the world is immune from the effects of this.
