Yes, stayed in the same place for 6 years, for no discernible reason other than I thought my opportunity was going to come, it never came, there were multiple changes in leadership and in the end the group i was in was dismantled and I could have been laid off (there were large layoffs just a couple weeks after I left).

So I'd definitely recommend staying sharp, looking at the market and moving when you think there isn't space for you to grow or change. Don't let your career stagnate with the business.
