100% (I have owned and worked at my own company for 10 years)

Anecdotally, I've also worked at many startups that became big companies through acquisition and Let me tell you - J&J has a lot of employees who have been there more than 5 years, thousands. They also had several big layoffs of such people during the process.

I work at salesforce. 100% of my immediate team and gotta be over 50% of my broader team. We’ve barely hired since 2020.
