Answer:
Moonlighting.
Step-by-step explanation:
Moonlighting is "when an individual takes up an alternative job different from the main job". An Individual working as an employee in a particular organization may decide to work after their normal working hours to earn double.
However, some organizations do not allow moonlighting because it might bring about the conflict of interest which is the reason most employees have another job without telling their employers and if caught might result in the termination of the main employment. In some government-owned organization, employees intending to get another job must inform the head of the department.
