Happens all the time in and around Our Nation’s Capital
Good observation!
It also happens in the academic world.
A person joins a college or university as an assistant professor at say age 30. For the next 25 years he or she works under a nine month contract. In reality a 24/7 calendar: 24 hours a week 7 month a year.
At age 55 the individual become a dean, associate dean or other non-teaching administration. And as we know colleges and universities abound with those positions.
Now the person get a nice raise and is on a 12 month contract. At retirement time, the pension is based on length of service, say 35 years and the average salary for the final 3 or 5 years of employment-the much higher administrator’s salaly. Proably an extra $25,000 to $50,000 a year for the next 20 or 30 years.
