Answer:
adaptive
Step-by-step explanation:
Adaptive change refers to the reintroduction of familiar or former regular practices (in this case business practices). It includes introducing changes that have already been experienced by the employees of the organization.
In this specific case, the same scenario repeats year after year during every holiday season. The employees already know that when December comes their schedule will be a mess, but it is a normal part of their job. That means that they have already adapted to the changes in their December work schedule.
