Under JSS thus far I’ve managed a minimum of 4 weekend days off per month, in both cases with one full weekend off and the other days saturdays with late reports on Sunday. Throw in some trips landing before 0900 on a Sunday and you can get a surprising amount of weekend time with the family if you live relatively close to LHR.
This is actually much much better than I used to get on a blind line, where the work left over was disproportionality low credit weekend work.
