質問: 作業 と 仕事 はどう違いますか? 作業 と 仕事 はどう違いますか?
回答: just like @zanera said, 作業is more like the work/labour/tasks you do at your 仕事 - work/workplace. the work at work. they are pretty interchangeble if you talk about finishing your tasks and such things (i've finished the tasks/work for today). but if you want to say that you've finished work (as in going home, not the tasks) or that you love your work, then i'd use 仕事
