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

'accessible work aim with old men' is the definition.
I can't judge whether this defines the answer.

'work aim with old men' is the wordplay.
'work' becomes 'op' (short for opus).
'aim' becomes 'end' (both can mean a goal or purpose).
'with old' becomes 'o' (common abbreviation eg in OE for Old English. I am not sure about the 'with' bit.).
'men' becomes 'OR' (military abbreviation for Other Ranks).
'op'+'end'+'o'+'or'='OPEN-DOOR'

Can you help me to learn more?

(Another definition for open-door that I've seen is " such a welcoming policy".)
