Rule catalogue · Teams and membership
A swap stays within one team, or none at all
Breaking it exchanges shifts between two different teams, so one team ends up short and the other over strength.
What teams and membership rules protect
Most air traffic control units roster in teams, and team membership carries real constraints: people move together, some units share staff, and some people belong to a pool rather than a team. These rules keep those structures intact so that a generated roster is one the unit can actually operate, rather than one that is optimal on paper and unrecognisable on the floor.
