I would say it depends on the conflict. If you have a carry over into the next month and an overlap, yeah, you dont get paid for both.

However if you end a month on a 5 day stretch with a clean end at the end, and bid a conflict 4 day to start the next month, its better to not have the 30/7 issue. They could clean up the next month to drop you to 6 days straight and if you are close to 30/7 (or really 29/7) you cant pick up anything on those conflict dropped days because youre at 29/7.

I like picking up red eye turns to end the month, because each one counts as 2 days worked, so try and snag one of the 28th and 30th, it will count as 4 days worked in a 31 day month. I bid a conflict 4 day to start the next month, once final schedule are out, I drop the red eye turns because everything is still green, and I score my conflict drop for the next month because I rarely see them drop the prior month to clean conflicts up. So there is the 8 days off, paid conflict, and now available to pick up a 4 day during IOT for the first of the new month.
