depends on your home life and how much yours / your families life revolves around being home.
If you’ve got young kids – or lots or pets or whatever then you’d probably prefer to have more of each day at home. If you don’t then you’d probably prefer to have more whole days off as its more opportunity to not be at home.
Personally I’ve always dislike working part days. Not least in my first job where all my hours were in the evening, so although I had most of the day ‘off’ you can’t relax and absorb yourself in anything because you work is looming. It didn’t help that the work was within a prison that I needed an escort into – if I wasn’t on time I couldn’t get into work at all.
So now even though I’ve been working for myself for the last 15 years I’m very binary – work all day (often til late at night) or all day off.
you’d get bank hols too (unless they’d be unpaid, so it could be a tactical decision!)
In that same job my sort of opposite number had the day shifts. My hours were spread across 3 evenings – his were on a monday and tues. Mostly on the monday though. We were sessional – no work no pay – so he lost about 10% or his yearly income to Bank Holidays
