In my 60+ years in the employment world I have not seen much change:
Immediated Gratification is the biggest change. Pre-1965 Delayd Graticification dominated. We sand We shall Overcome.
I returned from Vietnam. In 1968 we were chating When do we want it? We want it now!
Birth Control made the difference.
Individuaism v Collectivism is the 2d biggest change. There has always been a mix of Personal Responsibility and collect responsibility of the voluntary group of family, church, social club, etc. And involuntary responsibility of the local government, state government and national government. Individualism has declined. Voluntary responsibilith has declined. Mandatory responsibility has increased.
These two changes in the culture have changed the workplace. But the change is in the cutlure. The workplace reflects the culture.
