Every day, Sally, a staff member at Camp Bow Wow, takes dogs out of their kennels, and brings them to the doggy day care area, where the dogs are allowed to roam freely all day long. Now, Sally's boss, Sue, is telling Sally that dogs need rest time during the day, so she needs to take the dogs back and forth to their kennels twice a day, in addition to bringing the dogs out in the morning.

Sally's resistance to change is most likely due to which of the following factors?

Fear of the unknown

Lack of awareness

Habit

Social factors
