4 day work week coming to a job near you?...

Ive seen discussions of the 4 day work week since way before the Pandemic, and one thing i will never ever understand- and this isnt aimed at you, since it seems most people feel this way- is why , if you work 4 days in a week, why anyone would take Friday as their day off.. i would take Monday off in a heartbeat.. because at most workplaces, people are in a great mood on Fridays, so would seem to me like a more pleasant workday.. also, if you think Mondays suck with a five day workweek- just imagine how much Mondays would blow after a three day weekend every single week.. Tues-Fri workdays FTW .
But if people were mostly working Monday to Thursday, it'd be Thursday when people would be in a good mood.

Whereas working Tuesday to Friday, they'd still be in a good mood on Friday, but Monday would now be like Sunday and Tuesdays would suck.

Either way it's a three day weekend and four days work, the first day and the last day are always going to be what they are, doesn't really matter which actual day they are, right?
