Which option involves disciplinary action that allows an officer to work without pay?

The option that involves disciplinary action allowing an officer to work without pay is suspension. Suspension typically refers to a temporary removal from duty where the officer does not receive pay for the duration of the suspension. This disciplinary action underscores the seriousness of the misconduct while still leaving the door open for the officer to return to duty once the suspension period is completed.

In contrast, punishment on duty usually involves monitoring or directing an officer to perform their regular duties under scrutiny, which does not involve a loss of pay. A written reprimand is a formal letter or documentation that addresses the officer's behavior but does not involve any loss of pay or removal from their duties. Termination results in the officer losing their job altogether and consequently losing all pay, which is different from the temporary nature of a suspension. Thus, suspension is the appropriate option for this disciplinary action.
