Which of the following is a consequence of failing to report additional on-duty time?

Failing to report additional on-duty time can lead to potential legal penalties. This is because accurate reporting of work hours is critical for compliance with labor laws and regulations. When employees do not report all their hours, it can create violations related to wage and hour laws, thereby exposing both the individual and their employer to legal repercussions. These penalties can include fines, back wages owed to the employee, or other legal actions initiated due to non-compliance with statutory requirements surrounding work hours and pay.

The other options do not accurately reflect the consequences of not reporting additional on-duty time. Increased pay rate, license suspension, and job promotion are not directly associated with this issue and are unlikely outcomes as a result of failing to report hours worked. A focus on legal penalties underscores the importance of accurate time reporting as a fundamental responsibility for workers in order to avoid serious consequences for them and their employers.
