Very hard worker supports a mother (7)
I believe the answer is:
adamant
'very hard' is the definition.
'adamant' can be an answer for 'hard' (I've seen this before). I'm not sure about the 'very' bit.
'worker supports a mother' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'supports' is a charade indicator (letters next to each other) (bottom letters provide a support for the top ones).
'mother' becomes 'dam' (female parent of an animal).
'a'+'dam'='adam'
'ant' put after 'adam' is 'ADAMANT'.
Can you help me to learn more?
(Other definitions for adamant that I've seen before include "Positive or intransigent" , "Fabulous rock" , "Determined and unyielding to requests" , "unshakeable in purpose" , "Hard stone" .)
