why hierarchy in TCS is so messed up. I report to A who report to B who report to C who again report to A, how this can be called hierarchy?

Sounds less like a hierarchy and more like an infinity loop with a touch of deadlock, where reporting feels like debugging circular dependencies.

I feel like they have made this hierarchy that way so that any kind of approval won't go outside their managing circle. As if I want to go on a leave for a couple of days, the manager won't approve but he wants to go on leaves, it gets immediately approved.

it's even more messed up than it seems man, because of this crooked hierarchy getting exceptions seems like a mountain to conquer...

Actually they don't want individuals to escalate above that's why to make super seniors unknown they do this kind of shit

C is not actually reporting to A. C delegates his tasks to A. So A can do those tasks.

Power always lies with C only.

How this is possible? Is it some matrix kind of reporting structure coming due to client side way of working? But I am sure it won't be like that when it comes to Aprisal, SPEED.
