They’re different because of the job they do, who’s doing the monitoring and who has access to the records.

In all the examples you’ve given the monitoring is used to reduce the power imbalance between the public and vested interests with their own agenda.

For example, so the bank teller doesn’t steal from account holders.

For child care workers it’s to protect children in care. If it was used solely to gather information to fire potential whistleblowers people would have a problem with it too.

Considering that, for example, Meta management have a record of encouraging their staff to break copyright laws and lie about it, this surveillance probably isn’t designed to help society as a whole.
