'UN RESPONSABLE' SHOULD NOT BE TRANSLATED BY 'A RESPONSIBLE'

‘Un responsable’ is a false friend when translated from English to Spanish. You cannot translate this literally as the word ‘responsible’ is not a noun in English but it is an adjective. Thus, if we wanted to say ‘mi responsable es muy patiente conmigo’, we must not say ‘my responsible is very patient with me’. In fact, it needs to be ‘my manager is very patient with me’. So use the word ‘manager’ or ‘boss’ when you are talking about the person who leads or manages at work. Obviously, there are other translations of ‘un responsable’ such as ‘a supervisor’ or ‘a superior’.
Remember, in English, ‘responsible’ is an adjective so we could say ‘my manager is very responsible’.
