Because you have more than one boss

It’s not clear who your boss is.

In principle, you report to one person, but that person is rarely around to give you direction.

In practice, you report to another person, but that person doesn’t have the authority to give you direction.

Often, various others tell you what to do, but those people don’t have the expertise or experience to give you effective direction.

Invariably, the directions all these people give you are in direct conflict with each other.
