You really need to ask your HR Manager to provide you with the Job Description for both designations. A comparison of these will highlight any differences. These titles can vary from one organization to another. For example, in the 1960s, when I entered the job market, in one organization, the job hierarchy was as follows: Supervisor (3 grades), Chargehand (2 grades), Assistant Foreman, and Foreman, etc. A person of the Supervisory grade applied for a job in another organization for an Assistant Foreman's position, only to find that the job was of a lower grade than that of a Supervisor in that organization.

May I take this opportunity to inform you that we should check CiteHR first before asking a question, as it might have been covered in the past. I came across

I found that by Googling at
