The value of employees, customers, suppliers is never merely instrumental. A Kantian view would recognises that despite best efforts, uncontrollables do happen. Nevertheless Kantians would not allow individuals or groups to be sacrificed for collective self-interest. A utilitarian would evaluate consequences and maximise utility. But the Kantian would be accused of rigidity in making no allowances for extreme circumstances.
Categorical imperatives are absolutes.
Actions pass or fail. But the cracks appear in unlikely places. A manager may promise not to disclose information given in confidence by employees. The maxim is not logically consistent. This is moral relativism more than absolutism.
