'supermarket destroys clothes shop creating workforce issue' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'opening' is the wordplay.
I cannot really understand how this works, but
'opening' could be 'gap' (gap is a kind of opening) and 'gap' is located in the answer.
The remaining letters 'skills' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'of' is the link.
