Cashier

Cashier work is the most visible automation story in retail, and the machines are already on the floor. Self-checkout lanes, kiosks, mobile payment, and computer-vision stores take over scanning, bagging prompts, and payment — the loop that is most of the job. Stores still keep people at the front for interventions: theft and scan errors, age-restricted sales, returns, payment problems, and shoppers who need help. Some chains have even pulled back self-checkout where losses ran high. Federal projections still count about 3.2 million jobs and 542,600 openings a year, but employment is projected to fall about 10%, and the openings are churn, not growth. The work itself is steady where stores keep human lanes; the occupation is shrinking around it.

Treat cashiering as fast income and a first work record, not a destination. What separates a useful register job from a dead one: how many human lanes the store actually staffs, whether you rotate into stocking or the service desk, and whether anyone gets promoted out of the front end. A grocery or big-box job that cross-trains teaches more than a single-lane post — and single-lane posts are most of what gets posted. If the store is mid-conversion to self-checkout, expect fewer hours before fewer jobs; hours thin out first.
