There is no evidence anecdotal or otherwise to back this assertion.

Many stores near me appeared to cut cashiers before they added self-checkouts. If anything, adding self-checkouts increased the number of available options to get out of the store faster.

I'd place my bets on curbside pickup getting pushed more before cashiers get added given how popular it's become as an option.

Germany's discounters (ie, nearly all grocery stores) have long been hyper-efficient about checkouts. There is exactly one lane open until the line gets too long, then they open another. When the number of customers subsides, the second lane closes and the employee goes back to other tasks.

Only in recent years have self-checkouts started appearing in any significant number, and the formula hasn't changed. I guess theoretically stores might be able to cut back on employees, but it would be literally one or two people at most.

My anecdotal evidence is that one of the supermarkets I go to had 4-7 active cashiers and no self-checkout. After a complete redesign and renovation they have two active cashiers and self-checkouts. The self-checkout is closed unless there is a supervisor.
