Apologies if this is a silly question, but what is circadian rostering?
In essence it's a block of seven shifts (if the Sunday is worked) of late shifts with a similar start time, a couple of rest days, and then another seven (if the Sunday is worked) early shifts with a similar start time, before a long weekend of five days off.
It's "circadian" because the blocks of work are at a similar time, and there are less changes to the body clock (circadian rhythm) with the change between shifts at the midweek rest days and long weekend, rather than every week.
There are downsides to this though as you can't swap for a preferred shift or swap rest days.
I've spoken about it before here:
Hi All, I thought I'd start a separate thread on this subject. Does anyone have any thoughts or opinions about the pros and cons of being a Train Driver (starting as a Trainee of course) for Thameslink vs Great Northern? Many thanks

Thank you all for your replies, I have decided to stick with my original depot choice at WGC.
There is more variety at Welwyn - I would've picked there if I was you!
In the post I linked to above - since then (2021), Sundays have reverted to being entirely voluntary. [For the 2016 pay deal, either 8 or 12 Sundays per year had to be committed to (depending on your start date), but if Sundays in the working week hadn't been agreed by 2025 then they would revert to being entirely voluntary again. No talks on Sundays in the working week took place during this time!]
So if you don't want to work a Sunday, you can give it away still, but can also say you are 'not available' with seven days notice for ANY of your rostered Sundays. You no longer have a 'commitment' on any of them.
There have also been a lot of Drivers transfer out of Welwyn to be at depots closer to where they live, and so I understand there are actually vacancies at Welwyn now.
There did indeed become two links (rotas) at Welwyn, with one containing work on the Sevenoaks route.
