He's probably getting promoted, since he's finishing his work too quickly. You gotta learn to pace yourself. That was one thing I learned in my first corporate job. If you can finish something in a day but it's expected to take a week, don't rush. Whenever you hear the comment "wow, you finished that fast!", you know you screwed up.
In higher level positions, you're not paid for output, you're paid to be available when the shit hits the fan. Basically, you're an insurance policy.
You don't have even close to enough context to say something like that. And if it is a joke then it is of extremely bad taste about something that affect people's life and mental health.
