How do you know? Are you one of them?
I cannot speak for USA, but that was most definitely not the case in either Portugal or the UK. Responses from government departments in both countries virtually ceased. Only hearsay evidence but I am told the same happened in other countries.
People "working from home" do not. That is the problem. In an office situation I know many spend time on computers not actually working (thereby stealing from their employer who is paying them for that time - in public service cases you the taxpayer) but there is always somebody about that ensures at least some work is done.
I am aware from overheaing conversations on mobile phones that it also happens in private enterprise.
I am a Facilities Engineer for the US Government.
Goals, work assignments, and deadlines didn’t change. The majority of government workers, are white collar, and college educated. My annual construction projects, have to be in to the purchasing folks on set dates to allow for the required public bid time, and contract award needed before we can start. And we need to start soon enough to get done before fire season starts, or the snow flies. So, my work load can’t lag or slow down. For most of the people I work with are in the same kind of situation. Timber folks have to be ready to plant tress on last years fires, in the spring which there is still moisture on the ground to let them establish. Which means they need to let teh nursery know how many seedlings to get ready, by the end of November. Fire folks, have to interview, and hire seasonal fire folks in time to get them onboard and trained before fire season starts. River Patrol, Trails Construction Crews, Seasonal Recreation staffs needs to get hired. Lots of moving parts have to move by given dates, and you need to be ready on time, there is no way to delay things. Engineers, need to be ready to build things during the short time windows between the various time periods we are restricted from working because of species of concern.
Agencies have been reducing the time in office for at least a decade, and have been investing in cloud computer resources, to allow more mobile work. When Covid hit and we were ordered to work from home, the computer infrastructure was in place to make it possible.
In fact for many people things sped up. In the office a 20-gb/s service is shared among 60 to 100-people depending on the season. Most of us have a minimum of 10 or 20-gb/s at home. Downloading things from the cloud storage, took about a tenth of the time at home, that it does in the office now, with only a third of the people working in the building, and the rest remote.
Most folks don’t realize, a major portion of every agencies budget is rent for work spaces. And, Congress hasn’t increased that budget to keep pace with inflation. So, agencies get creative, Lower level employees are allowed 4-hours a week, in a shared cubical, at least nine other people use it the other 36-hours. The employees are providing their own home office space, for free without reimbursement other than the potential tax write off for maintaining a home office. There are shared conference rooms available for group and public meetings. If you need one you need to schedule and reserve it.
The work from home didn’t work for me, mostly because I have a large closet full of specialized equipment, which I need during the field season, and they wont give me a truck capable of carrying it. So, I have to spend time every day loading and unloading milk crates of tools and equipment. And, if they gave me the truck, it has to be returned to the yard every night. So, I start and end my day at the office for at least six months out of the year. Might was well work from there since I have to drive to and from daily.
