What you need are good laws, not so much a 4 day work week. I just go to the doctor during office hours and tell my employer I have to go. I even get paid time off for it, like everyone else working in this country. Same for the dentist or any other kind of medical thing.
Sure, it’s not always optimal if you work in some sort of shift, but they are required to make sure you can go.
By the way, not that I wouldn’t appreciate a 4 day work week, but this seems like a bit of a stretch to say that this is the reason why you would need one.
How does it damage the PN junction of the panel is open circuit or barely loaded? It doesn’t seem logical that this would damage the panel, but I’m open to being proven wrong.
There are all kinds of follow up questions to ask as well, but I think the main one is how big an effect are we talking?
