I would hold off on the core rules for a resume. If you are planning to stay in retail for a while, you can use the core roles to use in a retail CV.
I had an ETL-HR and Clerical help me with my resume and they gave me some wise advice. Basically, they said to list any technical or professional experience (other than Target) for a professional resume. If you don't have a lot of professional experience, then use Target to fill in your resume.
And not to be too wordy with your Target job history. Pick your top qualifications and experiences that you do on a regular basis. If they had you work on a project or cover for a TL during an extended absence, list that. Every company is going to know what you did for cashier, guest/customer service, food service, and salesfloor. If you worked in an area other than that. You may want to mention or summarize it a little bit more.
But Pharmacy Cashier may be a little more worth mentioning than a regular cashier.
Since I had some technical and professional experience outside of Target, I listed Target under an Employment category to explain the gap between my years of professional experiences. Then when I got enough professional experience, I dropped Target completely from my resume.
Another piece of wise advice I got was that mentioning an extensive amount of Target or any retail experience can actually hurt your resume by dulling it down too much. You want your resume to POP and stand out. So I summarized my Target experience in a simple one-line blurb...ex. "Experienced and trainer in customer relations, salesfloor, food services, and cashier functions for a major retail store chain."
And don't use Target lingo or acronyms, employers will not understand what zone, Planogram, ETL, GSTL, or POG mean.
