Some employees do not have to make any decisions on the job.
Until they do.
The employee that simply needs to stock the shelves at the grocery store might one day notice that the receiving supervisor is taking small bribes from suppliers who want priority in getting their trucks unloaded. That employee with a “no-decision job” now has a decision to make.
Do you have such employees working for you? Do you share your company values with them? Do you provide ethical decision-making training to them? Do you tell them about your reporting channels?
Low-level, no-decision employees are often front-line employees. Which means they are close to the customers, to the suppliers, even to the competitors. These interactions can be risky.
Removing decision-making from employees can reduce some risks, but it can also create others.
