The "gangplank" in the Scalar Chain principle emphasizes:

Direct communication for urgent matters

The correct answer is Option (4) → Direct communication for urgent matters

• In Henri Fayol’s principle of Scalar Chain, communication is expected to follow a formal chain of authority from top to bottom.

• However, to avoid delays in urgent situations, Fayol introduced the concept of the “gangplank”, which allows two employees at the same level to communicate directly without following the long chain, but with proper authority.
