Overworked miner with two shifts (4-4)

I believe the answer is:

time-worn

'overworked' is the definition.
(overworked can mean hackneyed or time-worn)

'miner with two shifts' is the wordplay.
'with' says to put letters next to each other.
'shifts' indicates anagramming the letters.
'miner'+'two'='minertwo'
'minertwo' with letters rearranged gives 'TIME-WORN'.

(Another definition for time-worn that I've seen is " Familiar through overuse".)

I've seen this clue in The Guardian.
