Where I work we have a website where we propose our ideas to make work more innovative. The employees boss has a say if the idea moves forward or not. Most of the time not.
The "through proper channel" rule in India govt administration seeks to ensure what the CEO wants. Also, the top bosses have at least two security walls protecting them, a peon who sits on a stool at the door to his office, and a personal assistant (secretary) who sits in a room that controls entry to the inner room where the boss sits. You have to ask permission from these two before you can see the boss. Letters (including email) have to be sent "through proper channel". There is a device called "Demi-official" (D-O) letter that theoretically permits a middle rank official to write to the boss, but D-O letters will be first seen by the secretary who will decide whether they are fit to be presented to the boss, or, the secretary will himself (or herself) send a reply or throw the letter into trash. Government rules such as CCS-CCA (Central Civil Services. [Classification, Control & Appeal]) Rules provide for "disciplinary action" against those who break the protocol.
