If it’s at the beginning of the month then, yes, you are right in line for an FA because that’s where the hotspots of uncovered work are. Leave the gap until later in the month and generally speaking you are safe.
Safer, sure, safe? not from what I’ve seen on LH but as we’ve drifted into Bidline tactics we are probably way off topic....the new joiners best just think JSS, optimisation (where you’ll never know that at one point in the process you actually had a roster with the days off you wanted/needed but then a trip got slotted in) and the fight to get Golden days........
