Rectify the work x Rectify the job

Hi guys,

A client called me today and asked me to return to her place to rectify a piece of work that I've done (it was a window graphic that I fitted on a window, and it's now falling off).

Which answer would be correct?

I will return to your place tomorrow to rectify the work.

Or

I will return to your place tomorrow to rectify the job.

Thanks in advance.
