UX Research - Is There a Difference Between Expertise and Tenure?

Sally Kohn: What is the difference between expertise and tenure? And how does that fit into job titles as it pertains to UX research? Kohn: I'm personally against the idea that if you work somewhere for 10 years, you get this title irrespective of the fact that you might not be good at that work. She says she's very lucky actually to be in a role of principle.
