Answer:
The correct answer here is Tacit or implicit.
Step-by-step explanation:
Tacit which is also a synonym for implicit means something that is implied from a statement or an assumption made and it is something that is expressed in a indirect way ,as nothing is stated clearly here.
In the blank given in the question , tacit fits right in , as an unethical practice by an individual employee or manager not only shows unethical behavior on his or her part but also on the management, it is not an personal issue but an organizational issue.
