At which point or job position is the amount of work the highest for people in the academic-researcher career?

Non-native English speaker here. 

I am referring to anyone above a PhD. That is postdocs, and those in the academic-researcher career ladder from Lecturer till Full Professor, Chair, Dean etc. 

At which job position or point along the career ladder is the amount of work the most for people in the academic-researcher career? What does this high amount of work and stress look like?

In general, the more early work you do (and the higher the quality of that work), the better the career. Thus, the work during graduate work and postdoc period (if there is one) and early years in a Tenure track job has the biggest impact on one's career - so a clever person is working their hardest then.
