Work experience is less important on academic CVs than standard industry CVs, but you should still include relevant work experience if you have it.
List teaching or lecturing experience in a separate teaching experience section. Group your teaching experience by category and order individual experiences by date, starting with the most recent experience.
You should include work experience outside of academia if it helps you explain gaps in your academic career and is relevant to the position you're applying for. Format non-academic work experience as you would in a standard CV. Don't go into detail about your responsibilities unless they help qualify you for the position you're applying for.
