When I started working in retail banking, four or five cashiers in the seven till positions at the branch might do 130+ transactions each a day at a cost of approximately £27 per transaction to the bank.

The ATM would take in cash and cheques but dispense more, and people became used to going to it for their cash. The cost to the bank was about £1 per transaction. With more people using the ATM, we dropped from seven till positions to four.

A call to telephone banking became the de rigueur way to connect with the bank for a decade. Hundreds of thousands of transactions could be enabled at a cost of about ten pence each for the bank. Four till positions became three.

When online banking came in the bank were able to action millions of daily transactions at a cost to them of less than a hundredth of a penny.

I drove past the bank branch I managed a few days ago; it is now a greengrocer’s.

If you work in L&D, the next shift is already here. Your colleagues are already using AI to do in minutes what used to take hours. And L&D teams are designing training for cashiers.
