post, employment, work
職 centers on a formal role or occupation: a post, employment, or the work one does in that role.
職 combines 耳 (ear) with 戠, which likely contributes the sound and relates to marking or recording. The idea of a post or duty may have developed from the notion of listening and recording in an official capacity.
The left side is an ear 耳, and the right side 戠 looks like a combination of sound 音 and a weapon 戈. Imagine a person whose job is to listen carefully and record important sounds, like a scribe or official at a post.
For ショク, imagine a shock at work when you get a new post: shock -> ショク, and the ear 耳 hears the surprising news about your employment.
