"Every morning I go to work by bus." No "my". "My work" seldom refers to a job. It's more often a reference to a general occupation*: "My work involves contact with all sorts of people."
PS * Hmm. This isn't a very satisfactory phrase. My point is that the speaker knows which specific job (or succession of jobs - in a sentence like 'My work has always been involved with communication of some sort"), but doesn't want to specify it; and the listener is satisfied with a general idea.
