Everyone thinks their own line of work is safe because everyone knows the nuances of their own job. But the thing that gets you is that the easier a job gets the fewer people are needed and the more replaceable they are. You might not be able to make a robot cashier, but with the scan and go mobile app you only need an employee to wave a scanner (to check that some random items in your cart are included in the barcode on your receipt) and the time per customer to do that is fast enough that you only need one person, and since anyone can wave a scanner you don’t have much leverage to negotiate a raise.
