How can American companies make the workplace environment safe and efficient without treating employees like suspected criminals?

Answer 1

Why do you think safety and efficiency is related to employer's paranoia?

Criminals work in varied jobs in prisons, they still have to work in safe environments, and somewhat efficiently.

If you operated a bank, would you double check bank tellers cash counts each day? Would you run security cameras and review them?

I am really not certain what exactly you are asking.
