This is actually not a big issue at EK, imho it's quite good here.
It depends somewhat on the equippment you're pushing and on your bidding style. A guy only 330 qualified tends to do more shorter flights, to build up hours he therefore works more shorter days giving him sometimes the minimum 8 days off. But I have to admit with the staffing getting better, this does not happen too often. The guys on the T7, and to a certain extent the 340 x-q-ones, can fly 2 ultralong trips plus one or two shorter ones, and they're done for the month, giving them up to 18 days off. Bidding helps to either avoid or desire ultralongs.
