Journos and their boss under the cosh? (7)

Ross

I believe the answer is:

pressed

I'm a little stuck... Click here to teach me more about this clue!

'journos and' is the definition.
I can't judge whether this definition defines the answer.

'boss under the cosh?' is the wordplay.
I cannot really see how this works, but
'boss' could be 'ed' (short for editor - newspaper boss) and 'ed' is found within the answer.
The remaining letters 'press' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'their' is the link.

Can you help me to learn more?

(Other definitions for pressed that I've seen before include "under some strain" , "crushed juice" , "Forced" , "Squeezed hard" , "Argued strongly and exerted force" .)
