'period of work' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'sixty minutes crew switched doris's' is the wordplay.
I cannot quite see how this works, but
'crew' could be 'eight' (an eight-person rowing team) and 'eight' is located in the answer.
'doris' could be 'day' (actress Doris Day is an example) and 'day' is located in the answer.
'sixty minutes' could be 'hour' (I've seen this in another clue) and 'hour' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
