Do people know?

[ppppoff]

It a work context. Do people that don't pull their weight know what they are doing? Do they secretly realise what they are doing by not working as much as their counterparts and just let others take up the slack? Or are they just oblivious to what others do compared to them?

I don't think there's one answer to this. Some people genuinely think they are working hard; some are working hard but they are not very good at the job; and some are consciously taking advantage, doing the minimum they think they can get away with.
