Adverse action includes threatening to take action of the type earlier described, or organising such action.
The essence of a threat is the communication of an intention to inflict harm on a person, made for the purpose of intimidating the person. However, a mere statement of an intention to harm a person does not necessarily constitute threatening the person. The statement of intention needs to be communicated directly to the target of the threat, or communicated in a way where it is intended or likely to find its way to the target.
