One day a week: definitely beneficial
Two days a week: probably
Three days a week: maybe.
Four days a week: Doubtful.
Five days a week: No!
But it also depends on the nature of your job. I was doing fine with one day a week until January 2023. They asked for three, I said fine. Then they asked for five and I told them it was time for me to retire and them to think about a transition plan. They backed off and said three was fine.
After a couple of months, I told them I was serious and suggested a specific colleague to replace me. The reality was that I was getting LESS work done not MORE with the added useless commute.
I put in my papers and they got the replacement I suggested so we made a very smooth transition versus other boomers who gave them two weeks notice (or less). My replacement, being a smart young man, told them that if three days commuting was good enough for me, it was good enough for him as well. They bought it.

99% of my work is done on the computer which works as well at home as at work. Now at work 1/5 of the people aren’t here because they’re working at home.
High speed internet has changed things both in the workplace and with social media. It isolates us.
