>No one is irreplaceable, and no one is an island.
I've watched a business fall apart slowly after the only developer on the legacy project left. Nobody knows the old framework, nobody wants to waste time learning something that won't advance their career, and finding an existing person familiar with it is search for a needle in a haystack.
A developer can find a new position in a matter of weeks. A business takes months to fill a position, then months more to ramp up as the new hire has to learn the unfamiliar code base. In a market with lots of competition, it can be catastrophic, but management has the mindset that we're all cogs until it's too late.
