I work 4 days on/2 off with a nightshift at the end of every 2nd cycle. When I work nights it’s actually a split shift, as in I work 0630 till 1130 then back in that night at 2230 till 0630, followed by a sleep day then 2 days off.
I’ll often ride in between the split shift but am usually far to tired to even think about riding after nights. Even driving home can be a bit dodgy at times.
With the other shifts if I’m too tired I won’t ride, if I’m not tired then I will.
I really shouldn’t grumble though. Apart from the night shift most shifts are 5-7 hours long plus I get 30 mins breaktime every couple of hours plus 36 days holiday a year (plus public).
