"Shot down" means that he said no, he dismissed the idea.

By asking "did it work?", I think zz1 is asking if dismissing the nap room idea resulted in people not staying longer.

I misread "shut down" instead: thank you for correcting me. Still: people respond to incentives and turning down an idea like that and letting the employees know that… this is an incentive and it may have lead to some results. So the question still stands.
