You're arguing over whether or not the workers are right. I'm saying it doesn't matter whether or not the workers are right. If the workers tell the boss "we don't know how to keep this server running", and then the server goes down, and the boss treats them badly, then the boss is morally wrong. If the boss is professional and says "well, we need someone who knows how to keep the server running, so we're going to hire someone else" then that's better. However, that's not what the boss did here, probably because (if your argument is true), the boss doesn't treat people very well and competent people wont work for him.
