As a receptionist in a company, you need to do reception, administration, personnel recruitment, cleaning, toilet cleaning and all kinds of chores. The boss of the company asked me to do it.

You need to make sure that your boss just wants to tell you the title or position of the executive director. If it's just a title, a job or a job, it's just a good name. If it's a position problem, then something needs to be redistributed by your boss. Otherwise, a director has no authority and is not as good as a normal employee.
