Job
Occupation, Work
noun, verbal noun, の adjective
You know 事 means "occurrence," but it can also mean "thing." So when you're doing things all day, what are you probably doing? A job! All jobs really just amount to doing things.
Just like "job" in English, 仕事 can refer to a person's specific occupation, to work in general, or to a particular task depending on the context.
This word uses the on'yomi reading for 仕 and the kun'yomi reading for 事. Please note that 事 uses the reading こと, which you didn't learn with the kanji, but you have come across it once or twice by now, and because of the way rendaku works, it's changed to the voiced ごと.
