We're having an issue of employee churn, and I think a lot of that is 20+ years of tech debt is catching up and new developments are becoming extremely difficult.

I was just wondering if it would be good general practice to refractor piecemeal every couple of years. This would (in theory) reduce tech debt, and if the refactoring is done by relative newbies, you ensure the base is understood and stays fresh.

I haven't hashed out or thought this through yet, so happy to have holes poked in this idea
