The law of work proportionate

Ever heard of the law “the effort taken by you is directly proportional the effort taken by your manager”.
Harder you work less the manager has to work and less you work harder the manager has to work.
Few days (infect months) back, I had a discussion with one of my friend (Who is in the course of becoming manager soon) regarding the relationship between manager and Subordinate working under him.
So, how does the performance of subordinate working under a manager affect him and is there any relationship between the efforts put in by them, or there is none….
You all must have noticed, when things are going fine in your project, you will see less of your manager and if thing are not going fine you will see more often your manager… so why does this happen…Is there any relationship between them. Let’s try to establish a relationship and provide a name to it for universal appeal.
Now the first question comes…when things go fine in a project?
There could be many internal and external factors affecting the project…but which is the most important factor, it’s you my dear friends, who work hard to keep the project in good shape and on time and yaa also your manger happy.
Your hard work will keep your manager out of pain and tension … in a sense less worry and less work for him.
Now consider the opposite of it, when a team under a manager is not giving 100 percent (there could be reasons for that, we will not go into that territory), what effect this could have on manager?
He would be a worried man with lots of tension and pain.
The outcome would be that you will see more of your manager, higher number of meetings, and some time helping with dirty (development) work…
So in short, we can say the more the subordinate work, lesser work, paint and worry for manager and less the subordinate work, higher work, pain and worry for manager.

Now let’s try to build a statement for the above prove… The law of work proportionate
Subordinate work is directly proportional to manager work.
Infect the better statement would be:
Manager work is directly proportional to Subordinate work.
