I think people mean that in the current environment and configuration of the team, they are indispensable. And that of course, can be true. The team would not be able to function without them. Of course a company can always find another fool to replace them. Many smaller businesses work that way. They have a core group of often arrogant and unskilled old-timers that for one reason or another, cannot and will not be fired. I've seen this more than once, with clients and companies I've worked for. The company cycles through talented new employees every other year. Once these employees are burnt out and move on to greener pastures, the company will find a new sucker to fill in their shoes. Rinse and repeat.
