Therefore in cc or any other organisation this divide and rule tactic is widespread. It is a way of gathering information or intelligence about the things that are going on.
Management has limited resources to reach out and getting the junior to spy on the seniors is one way of knowing whether these senior cc are working or shirking their responsibilities.
In like manner,the seniors are asked to appraised on the juniors and management would also used the results as one of the criterion for promotion or rewards.
CC needs to be more shrewd and counter the divide and rule tactic by banding together and talk good about each other. If you are shrewder than management you would be enjoying your work. However from what I've read in the comment space in my blog,cc aren't that smart after all. They simply fall into the trap set out by the management.
