The boss's office (11)

I believe the answer is:

managership

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

'the boss's office' is the definition.
'managership' can be an answer for 'office' (managership is a kind of office). I am not certain of the 'the boss's' bit.

'boss's office' is the wordplay.
'boss' becomes 'manager' (I've seen this in another clue).
'office' becomes 'ship' (I can't explain this - if you can you should give a lot more credence to this answer).
'manager'+'ship'='MANAGERSHIP'

Can you help me to learn more?

I've seen this clue in The Irish News.
