There are at least two meanings for Participation and it is most often misunderstood (again, most of the times at work)
Participation - Participate in decision making, take part in making something better and be part of some effort, take part in the learning process and try to make some meaningful contribution.
Participation - Claim ownership and be part of the results.
When we see more "Participation " than "Participation", then it is definite time to be vocal/bold. If you do not sow a seed or if you don't water/protect the plant, don't expect a fruit.
