Here outwork is the work a business sends out of the workshop, for people to do at home — sewing, packing, assembling small parts at a kitchen table. The factory keeps the machines; the “out” work happens in someone’s house, often paid by the piece. It is older British workplace language, close to what families in Taiwan call 家庭代工. You will not hear teenagers use it much; it belongs to history, labour talk, and a few older firms. Though actually the same spelling has other lives: a verb meaning “work harder than someone,” and an old military noun for a small fort outside the main wall. This entry is the home-work one. It is not overtime, and it is not a walk outside.
