I've seen our internal surveys go like this as well. They'll be critical on themselves with easy-to-solve issues but if it's something substantive then the polling will be very obtuse.
In my company (a famous company which builds trucks) they introduced those bullshit happiness surveys during Covid. So we coordinated so that the average of our marks were 1, 3, 4, 10, 5, 5, 10, 4, 3, 1, which is a Batman graph. Fortunately the “1” matches the first lockdown, but the managers are still wondering why the spikes at 10.
Reminds me about a cohort of colleagues at a place I worked that would have some fun conspiring similarly to this. Seemed HR and the company wanted everyone to fall in line. We called ourselves "the loose ends".
