Qitzur Shulchan Arukh – 185:3
Similarly if he gices his tallis to a worker to fix it as a job-worker [i.e. paid for doing a task, not per hour like in the previous se’if] and she [the tailor] brings it back during the day, he has the time of that entire day only [to repay her]. If she brings it to him at night, he has the time of the entire night alone.
However, the entire time that the tallis is in the hands / posession of the worker, even though she finished and completed her work, the owners is not in violation — even if it stays with the worker a number of days. Even if she informs him that he should bring her the money and take what is his [ie the tallis], in any case he is not violating [the prohibition against delayed payment of salary].
