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

'home' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'tube employee who operates from' is the wordplay.
I cannot quite understand how this works, but
'employee' could be 'worker' (I've seen this before) and 'worker' is located in the answer.
'from' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
This may be the basis of clue (or it may be nonsense).
