There is a Novel about this: Manna, by Marchall Brian. Their website that used to host it is down but here is the wayback version from 2019: https://web.archive.org/web/20190312023349/http://marshallbr...

In it, employees wore headsets run by the AI which instruct them task by task:

"Jane, when you are through with this customer, please close your register. Then we will clean the women's restroom."

Manna: "Place the 'wet floor' warning cone outside the door please."

When Jane completed the task, she would speak the word "OK" into her headset and Manna moved to the next step in the restroom cleaning procedure.

Manna: "Please block the door open with the door stop."

Jane: "OK."

Manna: "Please retrieve the bucket and mop from the supply closet."

Jane: "OK."
