I am trying to understand if ownership exists at all in a job. In sales, you can work hard on one account, and the account can be moved elsewhere for a number of reasons. In business development, you can manage a relationship and build a strategy just for the account manager to kick you out. In product management, you are supposed to be "the CEO of the product", the product owner, but even then priorities "change all the time". I am trying to identify job opportunities where I am assigned to work on something with specific R&R, and specific boundaries; a job where I know what I am responsible for. The aim is to focus on my work. I don't want to interfere in other colleagues' work, and I don't want others to invade what I am working on.
I want to believe there are jobs where R&R are well defined. So the question is:
How to identify roles where R&R and ownership are specific? (examples from different roles/industries, and different levels of seniority, are welcome)
