Hello Hedvart , Of the various meanings both words "work" and "job" have( when occurring as nouns) they identify in one and differ in many others. They both could mean the practiced labor and means for support and subsistence, the employment, one's occupation . I am a banker . This is my job or this is my work . In that case they could be identical . They vary on the other hand in many ways they are actually used : - One can go to work every day but not go to job . - Job is more specific in its objectives than work :" He has done a good job " here a job is a piece of work , a limited task to accomplish as part of his work assignments . "His work includes jobs that have to be handled meticulously". - Work has a broader meaning and it could encompass many areas of endeavor: for example 'work of art' something accomplished and produced by exerting effort and skill . It can't be a job of art . - work as a result or effect : the work of many hands. - People look for jobs , if there are no job openings they don't do any work . Jobs in this context is when you perform and get paid for it while work is when you prepare yourself and train yourself to get a job . You see how in certain contexts they can't be interchanged while in others they do.

I have a job, but I go to work. "work" can be a noun or a verb depending on the context, where as "job" will always be a noun (unless you are talking about a completely unrelated definition of "job" meaning to prod or stab)
