Not exactly. Many people in the operation support post will define it as a teller, but this is not exactly the case. Although there is a lot of overlapping work with tellers, in many cases, the main business of bank tellers is operational support, including IT, HR, administration and so on.

From the perspective of banking business, operational support is used as a backup for business operations. So it's not just front desk work, but also some middle and back office business.
