Screening calls is part of a secretary's job surely? I find that usually this happens when boss is busy working on something and only wants to be disturbed if really necessary. He will then divert his calls to my phone and I can then put through the urgent ones.
On other occasions, when someone dials his direct number and he does not recognise the number, he will then push the divert button and I will answer it - prevents him picking up his phone to cold sales calls.
As for the picture, why take offence at it? I would imagine it is only trying to represent an office environment - it doesn't look like me but does actually have a likeness to someone I work with
