That is silly. You have a job to do, you get the job done. Some days that takes 8 hours some days it takes 4 sometimes it means weekends, sometimes not. In the end it all evens out.
Remote employees should not be hourly, they should have a base salary to do a job. How long it takes them is all on them.
My brother is an architect, he has been working from home since COVID. He moved once they made them remote a hour north of the city they were in and has 10 acres now. He works, does stuff on the land, does more work....rinse and repeat. When his employer tried to make him come back to the office he said he would leave the firm, so they asked if they could ship his chair to him.
My BIL has been working from home for more than 20 years, he does the same basic thing.
Neither are hourly, both have a job and they do it.
