Those are the only two days you could have picked where it wouldn't make a difference. Either way you have 4 consecutive days of work followed by 3 free days.
Tuesday would immediately become the new Monday and everyone would get the Monday scaries. The start of a series of work days will always be a bummer, no matter what you call it.
We did four 10s at my last job, rotating every quarter whether you had off Monday or Friday. Personally I much preferred working the quieter Monday to the boring Friday. Tuesday became the new Monday as that’s when everyone was back in office. I didn’t feel the quiet Monday when you had half-ish the staff working was too bad, but the quiet Fridays really dragged. Quiet Monday was a nice ramp up to Tuesday, I got a lot of shit done on those Mondays.
I’d say there is a difference to which day you choose off. It doesn’t seem like there would be a difference but I definitely felt it.
Ok, I wasn't considering a rotation where the workplace would be partially staffed Mondays and Fridays. That makes a lot of sense. I was imagining everyone having off Saturday-Mondthatn a more universal weekend, which I think would not be practical for getting things accomplished. In that case I see what you mean about Mondays.
It was a hospital IT job so we couldn’t do everyone on the same schedule. My estimate would be 40% stayed on traditional M-F 8s, 30% on M-Th 10s, and 30% on Tu-F 10s. Quiet Monday was nice, quiet Friday really dragged, especially after lunch. I was way more productive working on Monday vs Friday.
The hybrid schedule worked pretty good for coverage, we also had staggered start times so there was always someone around M-F 6a-6p. Tuesday through Thursday was packed with meetings as that’s when you really had 100% of everyone working.
