Why should employers make sure employees take their vacations?

A.
They have a legal obligation.

B.
It is part of due diligence.

C.
It is a way that fraud can be uncovered.

D.
To ensure the employee does not get burnt out.

Explanation:
Many times employees who are carrying out fraudulent activities do not
take the vacation they have earned because they do not want anyone to find out what
they have been doing. Forcing employees to take vacations means that someone else
has to do that persons job and possibly uncover any misdeeds.
