What is the consequence for an employee if their department revokes their registration card?

If an employee's department revokes their registration card, the implication is generally that the employee loses the authorization to carry a firearm while on duty. Therefore, they may no longer be able to perform their duties in the same capacity as before. The potential consequence tied to continuing to work unarmed is that, if they can maintain their position without needing to carry a firearm, they might be allowed to continue their duties, albeit in a limited capacity or with specific restrictions.

It's important to understand that when a registration card is revoked, the individual loses certain privileges or qualifications associated with their role, particularly concerning armed duties. Therefore, the correct choice reflects the reality that they might still be employed in a less armed or potentially unarmed capacity, depending on the department's policies and requirements.
