"Job" is a countable noun. "Work" is uncountable. I've found a job! I've found (some) work!

A job has some meanings: - A position, with a company, of ongoing employment (I have a job) - an Individual task (I have a job for you (i have a task for you)) Work has some meanings - A verb, to perform labour as part of your job (i have to work) - A noun, to describe the state of an object (it doesn't work anymore / it is working now) - A noun, to describe the place where you have your job (I must go to work) - A noun, to describe the product of your labour (is this your work? did you make this?)

Could you expand the question?

Job is a noun. I have a job. I love my job. Work is a verb. I have to go to work. I love the work I do.
