I used to be a market research consultant and analyst.
From my perspective (opinion) - Having a questionnaire this open will be a nightmare to aggregate the different responses and even when you do, they won't fit nicely in to divisible responses. There will be lots of overlap and grey areas.
The survey is a good idea, but if there are a lot of people who respond the data will take a huge amount of time to clean (which can introduce subjective biases) and will have limited usefulness, because you can't cleanly determine relationships between answers. i.e did respondents who thought they didn't have a voice also see the reward system as negative etc.
