I had just spoken with an [Operations Control] employee at ZZZ. The employee had advised that s/he had felt uncomfortable when having to work the overnight hours and provide ramp control instructions. The employee confirmed that s/he had not received Ramp Controller [training].  I believe having the [Operations Control] employees provide ramp control instructions while simultaneously meeting the needs of their position (Zone Supervisor/Gate Manager) presents a safety risk.
Yesterday during an instructor-led training session; one of the [Operations Control] employees who has been provided with responsibility of issuing control instructions at ZZZ during the overnight hours indicated that he was unfamiliar with the taxiways.	 When speaking with him; he advised that the traffic; particularly at Concourse A; has been picking up recently. My feedback from speaking with some of the [Operations Control] employees is that they would rather not provide control instructions while simultaneously working their regular positions. Additionally; the [Operations Control] employee indicated that often times s/he would listen to the FAA control inform flight crews that ramp control is closed during these late hours.
Dispatcher reported that Airport Operations employee stated that they did not have required training to perform assigned duties.
