Screw being ill? (8,7)

Ross

I believe the answer is:

sickness benefit

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

'screw' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'ill?' is the wordplay.
I cannot quite understand how this works, but
'ill?' could be 'sick' ('sick' can be similar in meaning to 'ill') and 'sick' is located in the answer.
This may be the basis of clue (or it may be nonsense).

'being' acts as a link.

Can you help me to learn more?
