The only thing I can think of, that you don't get by staying at a business for a long amount of time (that does treat you well.. raises.. career progression.. etc.) is lack of exposure to how other businesses operate.

Some businesses operate in a bubble, and it's common for them to only explore what they need to. And by doing this, they're in danger of limiting their possibilities. I'm talking in terms of things as rudimentary as how one business manages their recruitment process vs another to the tools used in a development department vs another and why.

So if you are happy where you are, and plan to stay they for the indefinite future (and there's nothing wrong with that), I would just advise you to explore avenues outside of work that gives you exposure to the wider industry.

If you're an engineer that might be meetups.. talks.. perhaps courses.. If you're in an operational role, then maybe similar activities, but perhaps also ask your employer to allow you to explore other businesses with the intention of learning.
