If sb works for one company. In this company, there are 5 secretaries. He is one of the 5 secretaries.
Their duties are: answer the phone, translation, make contracts, decisions…
These 5 secretaries work together. The leader of these 5 secretaries is secretary to the manager.
So there are all 6 secretaries: 5 secretaries employees and one leader.
Can I say that these 6 persons work in a secretariat?
If no, what is the difference btw secretary and secretariat?
