You're old school...that model isn't going to work for the modern worker.
Adapt or die or have a bunch of culls punching in 8 hours trying to look busy...or hire people that are good at their job and quit worrying about when, where, and how they do it.
Give them the work and leave them alone...if it takes them 4 hours a day and 20 hours a week, great. If they want to work 10 hours a day and takes them 50 hours, great.
As long as the work is done, who cares?
I haven't shared my opinion. If you notice I am speaking in general views, not going into personal views.
The issue from an employers stand point is can someone provide enough value working 4 hours to justify full time pay. Few people have the skills to bring that kind of value as they would need to be worth a couple hundred $ an hour.
That model will work great for people who are really skilled and employers who are willing to pay. But that's more of a challenge for people who don't bring that much value to a business but expect to be paid the same.
It will be interesting to see how society reacts.
Will we be willing to pay more for products we buy so the people involved can work less which will require hiring more people to achieve the same output.
Will people be willing to pay higher taxes so the government employees can work less hours and have less than full time responsibility.
Will people pay more for homes, construction, etc so those people can work 20-30 hours instead of 70+.
Will people pay more for food so the cooks, waiters, etc can work less hours, less weekends, etc...
A poster pointed out earlier that the employees have a lot of power right now. Similar story for people who are selling real-estate, and used cars. That is likely to change over time and it will be interesting to see how the new way of thinking goes when jobs become scarce, homes become more available, lumber prices come down, car lots are full, used car market crashes, etc...
The group that really gets screwed in all this are the tradesmen, manufacturing, etc which can't be done remotely. So those folks will still be working 40+ hour weeks while some office folks are working 20 hours from home. I can see how those guys would get frustrated watching that unfold as the office folks will come out way ahead on working remotely.
As far as who cares. In a private business it's their money to do what they want with. Nobody really cares. In a government office it's a bit different as that's taxpayer $ so a different situation. In that situation taxpayers may have opinions on how that $ is spent.
I think it's really interesting to watch how this unfolds. The holy grail is finding a job someone can do part time on their own schedule and make really good $. Like Uber/grubhub/shop/ etc but people making $200+ an hour. The business that figures that model out will make a fortune as its' clear the demand is there from people wanting flexibility. This is why only fans has done so well, but not everybody want's to be a sex worker.
