'not something to worry about' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'it's different being under informal head?' is the wordplay.
'it's different' becomes 'other' (similar in meaning).
'being under' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'informal head?' becomes 'nob' (I've seen this in other clues. I am not sure about the 'informal' bit.).
'other' put after 'nob' is 'NO BOTHER'.
