Final answer:
The time period from the end of normal working hours on one day to the beginning of normal working hours the next workday is described as liberty, which is non-duty time not deducted from an employee's leave balance.
Step-by-step explanation:
From the end of normal working hours on one day to the beginning of normal working hours the next workday typically refers to liberty. This time is not officially counted as leave but is instead considered non-duty time for which an employee is not typically charged leave. Liberty is often used in military contexts to describe time off given to personnel, which does not count against their leave balance. It's the period when service members are free from duty and are not on the clock for their service. Whereas annual leave, sick leave, and compensatory leave require formal requests and are deducted from an employee's leave balance.
