We do. We adjust monetary supply for markets to be stable - money has been not backed by anything tangible for quite a while. Like with any proposed framework(also applies to monetary stuff) you find out how it affects outcomes and you adjust usage.
In the case of job levels, employees really shouldn’t be shortchanged into believing the job titles given to them. The remuneration is a better indicator when in doubt.
From decades of experience, I can state this is not true. Managers want workers that will benefit their own career. While in small businesses this might be aligned with 'a positive impact on the bottom line', the larger the business the less likely these objectives are likely to coincide.
+1! This is probably brutal but the most truthful fact not everyone can accept. This is especially true in big organisations. As much as we would like to believe that managers want workers to have a positive impact, that’s usually from the perspective of a manager who has a massive stake in the businesses, for eg, a founder or a small business owner.
Too many “managers” in big organisations are simply employees themselves who care more about their own survival and career, just as with the employees these managerial employees hire.
