Yeah, I know how it works but to use 7 or 8 days in one month and still have to work 16 days seems self induced. That’s 24.5 or 28 hrs credited to the month that you can drop. That’s most 4 days plus some. Most lines aren’t built to the min credit for the month so there’s usually a small buffer allowing you to drop a trip or two and not go below the min credit especially using that many vacation days. Even a 12 day off line has so many low credit trips crammed into the month, you should still be able to drop a few and not go below using 7 or 8 days. If you’re using less than that, say 1,2 or maybe 3 days, then yes, I can see having to pick back up after dropping a trip and working 15-16 days. All depends on how well you work the system I guess.
